The authors present preliminary results of searches for B mesons decaying into the charmless final states, using around 50 fb[sup -1] of data collected at the[Upsilon](4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. They describe measurements with the BaBar data of the branching fractions for B decays to charmless quasi-two-body final states containing[eta][prime] mesons.

With a sample of about 384 million B{bar B} pairs recorded with the BABAR detector, we search for the flavor-changing charged current transition B{sup ±} →?±? and perform an amplitude analysis of the effective flavor-changing neutral current transition B{sup ±} → {var_phi}(1020)K*(892)±. We also extend our search for other K* final states in the decay B° → {var_phi}(1020)K*0 with a large K*0 → K?− invariant mass. Two samples of events with one reconstructed hadronic B decay or one reconstructed semileptonic B decay are selected, and in the recoil a search for B{sup ±} →?±? is performed. We find a 2.6? (3.2? not including expected background uncertainty) excess in data which can be converted to a preliminary branching fraction central value of?(B{sup ±} →?±?) = (1.20{sup +0.40+0.29}{sub -0.38-0.30} ± 0.22) x 10−4. With the decay B{sup {+-}} → {var_phi}(1020)K*(892){sup {+-}}, twelve parameters are measured, where our measurements of f{sub L} = 0.49 {+-} 0.05 {+-} 0.03, f{sub {perpendicular}} = 0.21 {+-} 0.05 {+-} 0.02, and the strong phases point to the presence of a substantial helicity-plus amplitude from a presently unknown source.

The absolute branching fractions for the decays $D^-_s\rightarrow\ell^-\bar{\nu}_{\ell}$ ($\ell=e$, $\mu$, or $\tau$) are measured using a data sample corresponding to an integrated luminosity of 521 fb$^{-1}$ collected at center of mass energies near 10.58 GeV with the BABAR detector at the PEP-II $e^+e^-$ collider at SLAC. The number of $D_s^-$ mesons is determined by reconstructing the recoiling system $DKX\gamma$ in events of the type $e^+e^-{\rightarrow}DKXD^{*-}_s$, where $D^{*-}_s\rightarrow D^-_s\gamma$ and $X$ represents additional pions from fragmentation. The $D^-_s\rightarrow\ell^-\nu_{\ell}$ events are detected by full or partial reconstruction of the recoiling system $DKX\gamma\ell$. The following results are obtained: $B(D^-_s \to \mu^- \nu) = (6.02 \pm 0.38 \pm 0.34) \times 10^{-3}$, $B(D^-_s \to \tau^- \nu) = (5.00 \pm 0.35 \pm 0.49) \times 10^{-2}$, and $B(D^-_s \to e^- \nu)

The authors search for a new light non-Standard Model CP-odd Higgs boson, A°, decaying to??−,?+?−, and invisible in radiative decays of the?(2S) and?(3S). We search for the light scalar particle produced in single-photon decays of the?(3S) resonance through the process?(3S) 2!?A°, A° 2!invisible. We also search for evidence of an undetectable?(1S) decay recoiling against the dipion system. The data samples contain 99 x 106?(2S) and 122 x 106?(3S) decays collected by the BABAR detector at the SLAC PEP-II B factory.

These proceedings present the most up-to-date status of deep inelastic scattering (DIS) physics. Topics such as structure function measurements and phenomenology, quantum chromodynamics (QCD) studies in DIS and photoproduction, spin physics and diffractive interactions are reviewed in detail, with emphasis on those studies that push the test of QCD and the Standard Model to the limits of their present range of validity, towards both the very high and the very low four-momentum transfers in lepton-proton scattering.

The second volume in the CURRENT TOPICS IN NONCLINICAL DRUG DEVELOPMENT SERIES explores the critical issues and current topics in nonclinical drug development. This second volume covers individual topics and strategies in drug development from compound characterization to drug registration. Written by a variety of experts in the field, recent and rapid advances in technologies and associated changes in regulatory guidance are discussed. Select topics include: Evolution of Artificial Intelligence (AI) technologies and the impact on toxicologic pathology. Current approaches to carcinogenicity testing. Predicting drug-drug interactions. Current understanding of idiosyncratic drug reaction. Assessing cardiovascular risks beyond QT interval. Use of 3D cell cultures in toxicology and ADME. Development of small molecule-antibody complexes. Differentiating adverse from non-adverse findings in nonclinical studies. Current Topics in Nonclinical Drug Development: Volume 2 will aid toxicologists, toxicologic pathologists, consultants, regulators, study directors, and nonclinical scientists dealing with day-to-day issues encountered in drug development and assist in formulating strategies for resolution of these issues. In addition, the book will be a valuable reference for academicians and graduate students pursuing research related to nonclinical drug development.
