3. Digital health literacy and well-being in university students in Germany

Author: K Dadaczynski, M Messer, K Rathmann, and O Okan
Subjects: Public Health, Environmental and Occupational Health
Abstract: Background Digital communication technologies had a crucial role during the COVID-19 pandemic, with the internet and Social Media as highly frequented sources for retrieving health information. University student's health and well-being were highly affected and most interaction with peers and professionals migrated to the digital realm, which made digital health literacy (DHL) a key competence to navigate digital health environments. The main goal of the study was to explore DHL of students in Germany. Methods A cross-sectional online survey among students (N = 14916) from 130 universities in Germany was implemented as part of the global Covid-HL Network, collecting data on DHL, physical and mental health, SoC and sociodemographics. Data was analyzed using univariate, bivariate and regression analyses. Results Assessing the reliability of information (5964/14,103, 42.3%) and determining commercial interest of information posed the most difficult tasks (5489/14,097, 38.9%). Difficulties were revealed for finding information (4282/14,098, 30.4%). Female students reported lower DHL and social media use was associated with lower judgment skills. 38% of all students reported low and very low well-being and 29% reported at least two health complaints weekly, while health outcomes follow a social gradient (lower SES and gender). Regression analysis showed significant association between SoC and well-being (OR: 1.2-2.03) and health complaints (OR: 1.58-1.71). Higher future worries were with low well-being (OR: 2.83) and multiple health complaints (OR: 2.84). Conclusions There is an urgent need to enhance DHL and SoC of students and implement health promotion strategies, using target group specific intervention. Gender and socioeconomic differences must be taken into account and interventions could be delivered within the university. Measures should also address student mental health.

4. Evolution of milk oligosaccharides and lactose: a hypothesis

Author: T. Urashima, K. Fukuda, and M. Messer
Subjects: lactose, milk oligosaccharides, α-lactalbumin, lysozyme, lactation, prebiotics, Animal culture, SF1-1100
Abstract: Mammalian milk or colostrum contains up to 10% of carbohydrate, of which free lactose usually constitutes more than 80%. Lactose is synthesized within lactating mammary glands from uridine diphosphate galactose (UDP-Gal) and glucose by a transgalactosylation catalysed by a complex of β4-galactosyltransferase and α-lactalbumin (α-LA). α-LA is believed to have evolved from C-type lysozyme. Mammalian milk or colostrum usually contains a variety of oligosaccharides in addition to free lactose. Each oligosaccharide has a lactose unit at its reducing end; this unit acts as a precursor that is essential for its biosynthesis. It is generally believed that milk oligosaccharides act as prebiotics and also as receptor analogues that act as anti-infection factors. We propose the following hypothesis. The proto-lacteal secretions of the primitive mammary glands of the common ancestor of mammals contained fat and protein including lysozyme, but no lactose or oligosaccharides because of the absence of α-LA. When α-LA first appeared as a result of its evolution from lysozyme, its content within the lactating mammary glands was low and lactose was therefore synthesized at a slow rate. Because of the presence of glycosyltransferases, almost all of the nascent lactose was utilized for the biosynthesis of oligosaccharides. The predominant saccharides in the proto-lacteal secretions or primitive milk produced by this common ancestor were therefore oligosaccharides rather than free lactose. Subsequent to this initial period, the oligosaccharides began to serve as anti-infection factors. They were then recruited as a significant energy source for the neonate, which was achieved by an increase in the synthesis of α-LA. This produced a concomitant increase in the concentration of lactose in the milk, and lactose therefore became an important energy source for most eutherians, whereas oligosaccharides continued to serve mainly as anti-microbial agents. Lactose, in addition, began to act as an osmoregulatory molecule, controlling the milk volume. Studies on the chemical structures of the milk oligosaccharides of a variety of mammalian species suggest that human milk or colostrum is unique in that oligosaccharides containing lacto-N-biose I (LNB) (Gal(β1 → 3)GlcNAc, type I) predominate over those containing N-acetyllactosamine (Gal(β1 → 4)GlcNAc, type II), whereas in other species only type II oligosaccharides are found or else they predominate over type I oligosaccharides. It can be hypothesized that this feature may have a selective advantage in that it may promote the growth of beneficial colonic bacteria, Bifidobacteria, in the human infant colon.

Abstract: Objective The Trails-X is a new type of trail-making test that emphasizes executive function and does not require either literacy or numeracy. The purpose of this study was to examine performance variability across trails. Method Participants were the Trails-X standardization sample and individuals with traumatic brain injury (TBI), learning disabilities (LD), intellectual disabilities (ID), attention-deficit hyperactivity disorder (ADHD), and dementia. Trail-level performance was assessed via the mean Matrix, Connected Circles, and Time to Discontinue scores across trails. The Profile Variability Index (PVI) was calculated (Plake, Reynolds, & Gutkin, 1981) and clinical groups and standardization samples were compared via a one-way ANOVA. Results Across all trails, the mean Matrix score was 6 (possible range = 1-12) for the standardization sample and as low as 3 for the dementia and ID samples. The mean Connected Circles score was 16 (possible range = 0-22) and as low as 12 for the dementia sample. The mean Time to Discontinue score was 39 seconds (possible range = 1-75) and as high as 55 for the dementia sample. There was a statistically significant difference on the PVI score (F(5,845) = 6.921, p = .000). The dementia (M = 4.77) and ID (M = 5.11) samples had significantly lower (p < .05) PVI scores than the other samples, which were not significantly different from each other. Conclusions The dementia and ID samples were characterized by consistently low performance while the other samples were characterized by moderate amounts of variability, indicating that some variability across trails should be expected within less impaired individuals.

Abstract: Studies of race riots have identified several underlying conditions that contribute to their onset. This study builds on previous research and introduces an integrative approach for examining riots that includes the role of population characteristics, contextual factors, and cultural ideologies. An integrative approach is applied through a case study of the 1921 Tulsa Race Riot. In addition to highlighting relevant structural and contextual under pinnings, this approach also emphasizes the role of racial frames, or lenses through which racial groups view and interpret events and conditions differenctially.

Abstract: This research extends the theoretical concept of framing to the phenomenon of race riots using the Tulsa riot of 1921 as a case study. Media accounts of this riot published during 1921 illustrate both prognostic and diagnostic framing strategies and techniques and demonstrate how these processes affected official responses. Results of this research suggest that framing is a critical process associated with media and organizational representation of riots. Analyses indicate that the riot was officially attributed to an armed group of Black citizens whose goal was to protect one of its community members from a potential lynching. However, Black residents framed the riot differently in statements of their account of the events. A recurrent theme for both races and a number of media reports was that of inept and incompetent law enforcement officials. The authors suggest that prognostic solutions to riots (e.g., police strategies and tactics and reconciliatory attempts) are rooted in diagnostic assessments.

Abstract: X-ray absorption spectra of aqueous 4 and 6 M potassium hydroxide solutions have been measured near the oxygen K edge. Upon addition of KOH to water, a new spectral feature (532.5 eV) emerges at energies well below the liquid water pre-edge feature (535 eV) and is attributed to OH- ions. In addition to spectral changes explicitly due to absorption by solvated OH- ions, calculated XA spectra indicate that first-solvation-shell water molecules exhibit an absorption spectrum that is unique from that of bulk liquid water. It is suggested that this spectral change results primarily from direct electronic perturbation of the unoccupied molecular orbitals of first-shell water molecules and only secondarily from geometric distortion of the local hydrogen bond network within the first hydration shell. Both the experimental and the calculated XA spectra indicate that the nature of the interaction between the OH- ion and the solvating water molecules is fundamentally different than the corresponding interactions of aqueous halide anions with respect to this direct orbital distortion. Analysis of the Mulliken charge populations suggests that the origin of this difference is a disparity in the charge asymmetry between the hydrogen atoms of the solvating water molecules. The charge asymmetry is induced both by electric field effects due to the presence of the anion and by charge transfer from the respective ions. The computational results also indicate that the OH- ion exists with a predominately "hyper-coordinated" solvation shell and that the OH- ion does not readily donate hydrogen bonds to the surrounding water molecules.

Abstract: Oxygen K-edge X-ray absorption spectra (XAS) of aqueous chloride solutions have been measured for Li(+), Na(+), K(+), NH(4)(+), C(NH(2))(3)(+), Mg(2+), and Ca(2+) at 2 and 4 M cation concentrations. Marked changes in the liquid water XAS are observed upon addition of the various monovalent cation chlorides that are nearly independent of the identity of the cation. This indicates that interactions with the dissolved monovalent cations do not significantly perturb the unoccupied molecular orbitals of water molecules in the vicinity of the cations and that water-chloride interactions are primarily responsible for the observed spectral changes. In contrast, the addition of the divalent cations engenders changes unique from the case of the monovalent cations, as well as from each other. Density functional theory calculations suggest that the ion-specific spectral variations arise primarily from direct electronic perturbation of the unoccupied orbitals due to the presence of the ions, probably as a result of differences in charge transfer from the water molecules onto the divalent cations.

Abstract: The oxygen K edge X-ray absorption spectra of aqueous HCl and NaCl solutions reveal distinct perturbations of the local water molecules by the respective solutes. While the addition of NaCl leads to large spectral changes, the effect of HCl on the observed X-ray absorption spectrum is surprisingly small. Density functional theory calculations suggest that this difference primarily reflects a strong blue shift of the hydrated proton (in either the Eigen (H9O4+) or Zundel (H2O5+) forms) spectrum relative to that of H2O, indicating the tighter binding of electrons in H3O+. This spectral shift counteracts the spectral changes that arise from direct electrostatic perturbation of water molecules in the first solvation shell of Cl-. Consequently, the observed spectral changes effected by HCl addition are minimal compared to those engendered by NaCl. Additionally, these results indicate that the effect of monovalent cations on the nature of the unoccupied orbitals of water molecules in the first solvation shell is negligible, in contrast to the large effects of monovalent anions.

Abstract: Die Strahlentherapie des Prostatakarzinoms hat in den letzten Jahren bedeutende Fortschritte erzielt: Sowohl die Planung der Bestrahlung als auch die Bestrahlungstechniken sind heute besser und effizienter. In Abhangigkeit des jeweiligen Tumorstadiums stehen mit der perkutanen Strahlentherapie und der Brachytherapie verschiedene Optionen zur Verfugung, die in der Langzeitbeobachtung ahnlich gute Ergebnisse erreichen wie die radikale Operation. Die Verwendung dreidimensionaler Planungssysteme erlaubt eine immer grosere Dosiseskalation am Tumor, wobei gleichzeitig die Akut- und die Spattoxizitat vermieden bzw. zumindest reduziert werden konnen. Weisen die Patienten bereits ein fortgeschrittenes Prostatakarzinom auf bzw. haben sie ein hohes Risiko fur eine mogliche Lymphknotenmetastasierung, kann uber die Kombination beider Verfahren eine gute lokale Kontrolle erzielt werden. Auch eine zusatzliche antiandrogene Therapie kann bei diesen Patienten das krankheitsspezifische Uberleben verbessern. Ein Rezidiv nach radikaler Operation oder definitiver Strahlentherapie kann nach Ausschluss einer moglichen Metastasierung erneut in kurativer Intension strahlentherapeutisch behandelt werden. In der interdisziplinaren Behandlung hat die Strahlentherapie demnach heute ihren festen Platz, sie setzt jedoch einen uneingeschrankten Dialog zwischen Urologen und Strahlentherapeuten voraus. Radiotherapy of prostate cancer has gained great progress during the last years - 3 d planning and irradiation techniques are more efficient today. Depending on tumour stage external beam irradiation (EBRT) and brachytherapy offer different options for primary treatment achieving equal results in long term follow up compared to surgery. The use of 3d treatment planning systems allows a progressive dose escalation at the tumour site omitting or reducing acute and late toxicity. In patients with advanced carcinoma or at high risk of lymph node metastasis a combination of EBRT and brachytherapy is able to achieve good local control. An additional antiandrogen therapy can improve disease specific survival. Even tumour relapse after radical prostatectomy or definitive irradiation can be treated with irradiation in curative intension after exclusion of distant metastases. Today radiotherapy is well established in interdisciplinary treatment of prostate cancer but requires an unrestricted dialogue between urologists and radiotherapists.

Abstract: An overview of the strangeness measurements made by the STAR collaboration at RHIC for Au-Au collisions at √s NN = 130 and 200 GeV plus p-p collisions at √s NN = 200 GeV is presented. A wealth of information has been generated on the kinematics and scale of strange particle production by this experiment. When viewed in combination a picture emerges of particles demonstrating a surprisingly high degree of collective motion, suggestive of strong internal pressure within the source which builds up rapidly. The non-resonance yields are consistent with statistical hadron formation. Although there appears to be a rapid decoupling of the source, resonance particle measurements show signs of rescattering during the hadronic phase. Meanwhile the observed suppression of high momentum probes and their large azimuthal asymmetry indicate that this hot dense matter has significant interactions with particles moving through it.

Abstract: Values of the ratios in the mid-rapidity yields of Λ / Λ =0.71±0.01( stat. )±0.04( sys. ) , Ξ + / Ξ − =0.83±0.04( stat. )±0.05( sys. ) , Ω + / Ω − =0.95±0.15( stat. )±0.05( sys. ) and K + /K − =1.092±0.023(combined) were obtained in central s NN =130 GeV Au+Au collisions using the STAR detector. The ratios indicate that a fraction of the net-baryon number from the initial system is present in the excess of hyperons over antihyperons at mid-rapidity. The trend in the progression of the baryon ratios, with increasing strange quark content, is similar to that observed in heavy-ion collisions at lower energies. The value of these ratios may be related to the charged kaon ratio in the framework of simple quark-counting and thermal models.

19. La Société des Vétérinaires Fribourgeois et Martin Strebel

Author: M. Messer
Subjects: General Veterinary
Abstract: Der Verein Freiburger Tierarzte wurde am 24. April 1852 in Freiburg gegrundet. Zu Beginn beschaftigte sich der Verein vor allem mit der Seuchen situation, die auch zur Grundung gefuhrt hatte. An den Versammlungen wurden aber auch Probleme zwischen praktisch ausgebildeten und wissenschaftlich tatigen Kollegen diskutiert. Interessant die Tatsache, dass zu jener Zeit die jungen Tierarzte im Kanton Freiburg eine kantonale Prufung absolvieren mussten. Seit der Grundung wurde der Verein in der Person von Martin Strebel stark gepragt, der von 1874 bis 1902 auch Prasident des Vereins Freiburger Tierarzte war. Martin Strebel war ein guter Praktiker, beschaftigte sich aber auch mit wissenschaftlichen Fragestellungen sowohl auf Kantons- wie auf Bundesebene. Rasch wurde er uber die Landesgrenzen bekannt und seine Publikationen sind noch heute in den Nachbarlandern zu finden. Der Verein Freiburger Tierarzte kann auf eine Personlichkeit wie Martin Strebel als Grundungsmitglied mit Recht stolz sein.

Abstract: The STAR detector has made a variety of measurements of strange and other hadronic species in Au+Au collisions at s N N = 130 GeV. A comparison of kaon and pion production enables an examination of the systematics of strangeness production with energy by comparing them to lower energy collisions. Anti-baryon to baryon ratios indicate a much reduced net-baryon density and transverse momentum spectra show that a picture of transverse expansion seems appropriate.

Abstract: We present results for the charged-particle multiplicity distribution at midrapidity in Au-Au collisions at square root of [s(NN)] = 130 GeV measured with the PHENIX detector at RHIC. For the 5% most central collisions we find dN(ch)/d eta(vertical line eta = 0) = 622+/-1(stat)+/-41(syst). The results, analyzed as a function of centrality, show a steady rise of the particle density per participating nucleon with centrality.

Abstract: During the 1996 lead run time, CERES has accumulated 42 million events, corresponding to a factor of 5 more statistics than in 1995 and 2.5 million events of a special photon-run. We report on the results of the low-mass e$^+$e$^-$-pair analysis. Since the most critical item is the poor signal-to-background ratio we also discuss the understanding of this background, in absolute terms, with the help of a detailed Monte Carlo simulation. We show preliminary results of the photon analysis and summarize the results of the hadron analysis preliminarily reported on already at QM'97, 10 pages, 9 figures, Proceedings of the XIV Int.

Abstract: The in vitro activity of LY264826, a novel glycopeptide antibiotic produced by Amycolatopsis orientalis, was compared with those of vancomycin, teicoplanin, and oxacillin against 311 gram-positive clinical isolates from patients with cancer, LY264826 had lower MICs for 90% of isolates (MIC90) than vancomycin for all species tested. It was active against oxacillin-resistant isolates including Staphylococcus aureus (MIC90, 0.5 micrograms/ml), Staphylococcus haemolyticus (MIC90, 2.0 micrograms/ml), Enterococcus spp. (MIC90, 0.5 micrograms/ml), Bacillus cereus (MIC90, 0.25 micrograms/ml), and Corynebacterium jeikeium (MIC90, 0.12 micrograms/ml). For S. aureus, including oxacillin-resistant isolates, the MICs of LY264826 were similar to those of teicoplanin. For coagulase-negative staphylococci, however, LY264826 had MICs that were 4- to 32-fold lower than those of teicoplanin. Against most streptococcal species the activities of LY264826 and teicoplanin were similar. Bactericidal activity against Staphylococcus spp. and most Streptococcus pyogenes isolates was less than or equal to 1 dilution of the MIC. One isolate of S. pyogenes and all Enterococcus faecalis strains tested were tolerant of LY264826, with MBCs greater than or equal to 32-fold greater than the MICs. The addition of 50% human serum resulted in a significant increase in activity only against Staphylococcus epidermidis. Variations in pH from 6.4 to 8.4 and in inoculum from 10(3) to 10(7) CFU/ml did not significantly affect the activity of LY264826.

27. Probing the local structure of liquid water by X-ray absorption spectroscopy

Abstract: It was recently suggested that liquid water primarily comprises hydrogen-bonded rings and chains, as opposed to the traditionally accepted locally tetrahedral structure (Wernet et al. Science 2004, 304, 995). This controversial conclusion was primarily based on comparison between experimental and calculated X-ray absorption spectra (XAS) using computer-generated ice-like 11-molecule clusters. Here we present calculations which conclusively show that when hydrogen-bonding configurations are chosen randomly, the calculated XAS does not reproduce the experimental XAS regardless of the bonding model employed (i.e., rings and chains vs tetrahedral). Furthermore, we also present an analysis of a recently introduced asymmetric water potential (Soper, A. K. J. Phys.: Condens. Matter 2005, 17, S3273), which is representative of the rings and chains structure, and make comparisons with the standard SPC/E potential, which represents the locally tetrahedral structure. We find that the calculated XAS from both potentials is inconsistent with the experimental XAS. However, we also show the calculated electric field distribution from the rings and chains structure is strongly bimodal and highly inconsistent with the experimental Raman spectrum, thus casting serious doubt on the validity of the rings and chains model for liquid water.

Abstract: Measurements of the oxygen K-edge X-ray absorption spectrum (XAS) of aqueous sodium halide solutions demonstrate that ions significantly perturb the electronic structure of adjacent water molecules. The addition of halide salts to water engenders an increase in the preedge intensity and a decrease in the postedge intensity of the XAS, analogous to those observed when increasing the temperature of pure water. The main-edge feature exhibits unique behavior and becomes more intense when salt is added. Density functional theory calculations of the XAS indicate that the observed red shift of the water transitions as a function of salt concentration arises from a strong, direct perturbation of the unoccupied molecular orbitals on water by anions, and does not require significant distortion of the hydrogen bond network beyond the first solvation shell. This contrasts the temperature-dependent spectral variations, which result primarily from intensity changes of specific transitions due to geometric rearrangement of the hydrogen bond network.

Abstract: We present the first large-acceptance measurement of event-wise mean transverse momentum fluctuations for Au-Au collisions at nucleon-nucleon center-of-momentum collision energy root s(NN) = 130 GeV. The observed nonstatistical fluctuations substantially exceed in magnitude fluctuations expected from the finite number of particles produced in a typical collision. The r.m.s. fractional width excess of the event-wise distribution is 13.7 +/- 0.1(stat) +/- 1.3(syst)% relative to a statistical reference, for the 15% most-central collisions and for charged hadrons within pseudorapidity range vertical bar eta vertical bar fluctuation excess is qualitatively larger than those observed at lower energies and differs markedly from theoretical expectations. Contributions to fluctuations from semihard parton scattering in the initial state and dissipation in the bulk colored medium are discussed.

Abstract: We report inclusive photon measurements about midrapidity (\y\ gammagamma decay channel. The fractional contribution of the pi(0)-->gammagamma decay to the inclusive photon spectrum decreases by 20%+/-5% between p(t)=1.65 GeV/c and p(t)=2.4 GeV/c in the most central events, indicating that relative to pi(0)-->gammagamma decay the contribution of other photon sources is substantially increasing.

Abstract: We report on the rapidity and centrality dependence of proton and anti-proton transverse mass distributions from {sup 197}Au + {sup 197}Au collisions at {radical}s{sub NN} = 130 GeV as measured by the STAR experiment at RHIC. Our results are from the rapidity and transverse momentum range of |y| < 0.5 and 0.35 < p{sub t} < 1.00 GeV/c. For both protons and anti-protons, transverse mass distributions become more convex from peripheral to central collisions demonstrating characteristics of collective expansion. The measured rapidity distributions and the mean transverse momenta versus rapidity are flat within |y| < 0.5. Comparisons of our data with results from model calculations indicate that in order to obtain a consistent picture of the proton(anti-proton) yields and transverse mass distributions the possibility of pre-hadronic collective expansion may have to be taken into account.

Abstract: Transverse momentum spectra and yields of hadrons are measured by the PHENIX collaboration in Au+Au collisions at √s NN =130 GeV at the Relativistic Heavy Ion Collider. The time-of-flight resolution allows identification of pions to transverse momenta of 2 GeV/c and protons and antiprotons to 4 GeV/c. The yield of pions rises approximately linearly with the number of nucleons participating in the collision, while the number of kaons, protons, and antiprotons increases more rapidly. The shape of the momentum distribution changes between peripheral and central collisions. Simultaneous analysis of all the p T spectra indicates radial collective expansion, consistent with predictions of hydrodynamic models. Hydrodynamic analysis of the spectra shows that the expansion velocity increases with collision centrality and collision energy. This expansion boosts the particle momenta, causing the yield from soft processes to exceed that for hard to large transverse momentum, perhaps as large as 3 GeV/c.

Abstract: We present STAR measurements of the azimuthal anisotropy parameter v{sub 2} and the binary-collision scaled centrality ratio R{sub CP} for kaons and lambdas ({Lambda} + {bar {Lambda}}) at mid-rapidity in Au+Au collisions at {radical}s{sub NN} = 200 GeV. In combination, the v{sub 2} and R{sub CP} particle-type dependencies contradict expectations from partonic energy loss followed by standard fragmentation in vacuum. We establish p{sub T} {approx} 5 GeV/c as the value where the centrality dependent baryon enhancement ends. The K{sub S}{sup 0} and {Lambda} + {bar {Lambda}} v{sub 2} values are consistent with expectations of constituent-quark-number scaling from models of hadron formation by parton coalescence or recombination.

Abstract: Elliptic flow and two-particle azimuthal correlations of charged hadrons and high-${p}_{T}$ pions (${p}_{T}g1\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/c$) have been measured close to midrapidity in $158A\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/c$ $\mathrm{P}\mathrm{b}+\mathrm{A}\mathrm{u}$ collisions by the CERES experiment. Elliptic flow (${v}_{2}$) rises linearly with ${p}_{T}$ to a value of about $10%$ at $2\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/c$. Beyond ${p}_{T}\ensuremath{\approx}1.5\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/c$, the slope decreases considerably, possibly indicating a saturation of ${v}_{2}$ at high ${p}_{T}$. Two-pion azimuthal anisotropies for ${p}_{T}g1.2\text{ }\text{ }\mathrm{G}\mathrm{e}\mathrm{V}/c$ exceed the elliptic flow values by about $60%$ in midcentral collisions. These nonflow contributions are attributed to nearside and back-to-back jetlike correlations, the latter exhibiting centrality dependent broadening.

Abstract: Extensive experimental data from high-energy nucleus-nucleus collisions were recorded using the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). The comprehensive set of measurements from the first three years of RHIC operation includes charged particle multiplicities, transverse energy, yield ratios and spectra of identified hadrons in a wide range of transverse momenta (p_T), elliptic flow, two-particle correlations, non-statistical fluctuations, and suppression of particle production at high p_T. The results are examined with an emphasis on implications for the formation of a new state of dense matter. We find that the state of matter created at RHIC cannot be described in terms of ordinary color neutral hadrons., Comment: 510 authors, 127 pages text, 56 figures, 1 tables, LaTeX. Submitted to Nuclear Physics A as a regular article; v3 has minor changes in response to referee comments. Plain text data tables for the points plotted in figures for this and previous PHENIX publications are (or will be) publicly available at http://www.phenix.bnl.gov/papers.html

Abstract: We report the first observations of the first harmonic (directed flow, v(1)) and the fourth harmonic (v(4)), in the azimuthal distribution of particles with respect to the reaction plane in Au+Au collisions at the BNL Relativistic Heavy Ion Collider (RHIC). Both measurements were done taking advantage of the large elliptic flow (v(2)) generated at RHIC. From the correlation of v(2) with v(1) it is determined that v(2) is positive, or in-plane. The integrated v(4) is about a factor of 10 smaller than v(2). For the sixth (v(6)) and eighth (v(8)) harmonics upper limits on the magnitudes are reported.

Abstract: We present the results of charged particle fluctuations measurements in Au+Au collisions at rootS(NN)=130 GeV using the STAR detector. Dynamical fluctuations measurements are presented for inclusive charged particle multiplicities as well as for identified charged pions, kaons, and protons. The net charge dynamical fluctuations are found to be large and negative providing clear evidence that positive and negative charged p article production is correlated within the pseudorapidity range investigated. Correlations are smaller than expected based on model-dependent predictions for a resonance gas or a quark-gluon gas which undergoes fast hadronization and freeze-out. Qualitative agreement is found with comparable scaled p+p measurements and a heavy ion jet interaction generation model calculation based on independent particle collisions, although a small deviation from the 1/N scaling dependence expected from this model is observed.

Abstract: We report measurements of single-particle inclusive spectra and two-particle azimuthal distributions of charged hadrons at high transverse momentum (high p(T)) in minimum bias and central d+Au collisions at sqrt[s(NN)]=200 GeV. The inclusive yield is enhanced in d+Au collisions relative to binary-scaled p+p collisions, while the two-particle azimuthal distributions are very similar to those observed in p+p collisions. These results demonstrate that the strong suppression of the inclusive yield and back-to-back correlations at high p(T) previously observed in central Au+Au collisions are due to final-state interactions with the dense medium generated in such collisions.

Abstract: The balance function is a new observable based on the principle that charge is locally conserved when particles are pair produced. Balance functions have been measured for charged particle pairs and identified charged pion pairs in Au + Au collisions at √(sNN) = 130 GeV at the Relativistic Heavy Ion Collider using STAR. Balance functions for peripheral collisions have widths consistent with model predictions based on a superposition of nucleon-nucleon scattering. Widths in central collisions are smaller, consistent with trends predicted by models incorporating late hadronization.

Abstract: Azimuthal correlations for large transverse momentum charged hadrons have been measured over a wide pseudorapidity range and full azimuth in Au+Au and p+p collisions at roots(NN)=200 GeV. The small-angle correlations observed in p+p collisions and at all centralities of Au+Au collisions are characteristic of hard-scattering processes previously observed in high-energy collisions. A strong back-to-back correlation exists for p+p and peripheral Au+Au. In contrast, the back-to-back correlations are reduced considerably in the most central Au+Au collisions, indicating substantial interaction as the hard-scattered partons or their fragmentation products traverse the medium.

Abstract: The PHENIX detector is designed to perform a broad study of A-A, p-A, and p-p collisions to investigate nuclear matter under extreme conditions. A wide variety of probes, sensitive to all timescales, are used to study systematic variations with species and energy as well as to measure the spin structure of the nucleon. Designing for the needs of the heavy-ion and polarized-proton programs has produced a detector with unparalleled capabilities. PHENIX measures electron and muon pairs, photons, and hadrons with excellent energy and momentum resolution. The detector consists of a large number of subsystems that are discussed in other papers in this volume. The overall design parameters of the detector are presented. (C) 2002 Elsevier Science B.V.

Abstract: We report high statistics measurements of inclusive charged hadron production in Au+Au and p+p collisions at sqrt[s(NN)]=200 GeV. A large, approximately constant hadron suppression is observed in central Au+Au collisions for 5p(T)12 GeV/c. The collision energy dependence of the yields and the centrality and p(T) dependence of the suppression provide stringent constraints on theoretical models of suppression. Models incorporating initial-state gluon saturation or partonic energy loss in dense matter are largely consistent with observations. We observe no evidence of p(T)-dependent suppression, which may be expected from models incorporating jet attenuation in cold nuclear matter or scattering of fragmentation hadrons.

Abstract: Data from the first physics run at the Relativistic Heavy-Ion Collider at Brookhaven National Laboratory, Au+Au collisions at $\sqrt{s_{NN}}=130$ GeV, have been analyzed by the STAR Collaboration using three-pion correlations with charged pions to study whether pions are emitted independently at freezeout. We have made a high-statistics measurement of the three-pion correlation function and calculated the normalized three-particle correlator to obtain a quantitative measurement of the degree of chaoticity of the pion source. It is found that the degree of chaoticity seems to increase with increasing particle multiplicity., 6 pages, 4 figures, published in PRL

Abstract: We report the first observation of $K^{\star}(892)^{0}\to\pi K$ in relativistic heavy ion collisions. The transverse momentum spectrum of $(K^{\star0}+\bar{K}^{\star0})/2$ from central Au+Au collisions at $\sqrt{s_{_{NN}}}=130$ GeV is presented. The ratios of the $K^{\star0}$ yield derived from these data to the yields of negative hadrons, charged kaons, and $\phi$ mesons have been measured in central and minimum bias collisions and compared with model predictions and comparable $e^{+}e^{-}$, $pp$, and $\bar{p}p$ results. The data indicate no dramatic reduction of $K^{\star0}$ production in relativistic heavy ion collisions despite expected losses due to rescattering effects.

Abstract: Two-particle azimuthal correlation functions are presented for charged hadrons produced in Au+Au collisions at the Relativistic Heavy Ion Collider (sqrt[sNN]=130 GeV). The measurements permit determination of elliptic flow without event-by-event estimation of the reaction plane. The extracted elliptic flow values (v2) show significant sensitivity to both the collision centrality and the transverse momenta of emitted hadrons, suggesting rapid thermalization and relatively strong velocity fields. When scaled by the eccentricity of the collision zone e, the scaled elliptic flow shows little or no dependence on centrality for charged hadrons with relatively low pT. A breakdown of this e scaling is observed for charged hadrons with pT >1.0 GeV/c.
