Abstract
503 Background: Intermediate hepatocellular carcinoma is a heterogenous group of disease. We aimed to prognosticate survival after surgical resection of HCC stratified by stage with amalgamation of the modified Barcelona Clinic Liver Cancer (BCLC) staging system and location of tumour. Methods: This single-institutional retrospective cohort study included patients with HCC who underwent surgical resection between 1st January 2000 to 30th June 2016. Participants were divided into 6 different subgroups based on the Milan Criteria (MC), the “Up-to-7” criteria, and location of lesions: A-u) Within MC with Unilobar lesions; A-b) Within MC + Bilobar lesions; B1-u) Out of MC + within Up-To-7 + Unilobar lesions; B1-b) Out of MC + within Up-to-7 + Bilobar lesions; B2-u) Out of MC + Out of Up-To-7 + Unilobar lesions; B2-b) Out of MC + Out of Up-To-7 + Bilobar lesions. A separate survival analysis was conducted for solitary HCC lesions according to three subgroups: A-S (Within MC); B1-S (Out of MC + within Up-To-7); B2-S (Out of MC + out of Up-To-7). The respective primary and secondary time-to-event outcomes were overall survival (OS) and recurrence-free survival (RFS). Results: 794 of 1043 patients with surgical resection for HCC were analysed. Groups A-u (64.6 %), A-b (58.4 %) and B1-u (56.2 %) had 5-year cumulative overall survival (OS) rates above 50% after surgical resection and median OS exceeding 60 months (P=0.0001). The 5-year cumulative recurrence-free survival rates (RFS) were 40.4% (group A-u), 38.2% (group A-b), 36.3% (group B1-u), 24.6% (group B2-u), and 7.3% (group B2-b)(P=0.0001). For solitary lesions, the 5-year OS for the subgroups were A-S (65.1%), B1-S (56.0%) and B2-S (47.1%) (P=0.0003). Compared to A-S, there was also a significant trend towards relatively poorer OS as the lesion sizes increased in B1-S (HR 1.46, 95%CI 1.03 – 2.08) and B2-S (HR 1.65, 95%CI 1.25 – 2.18). Conclusions: We adopted a novel approach combining the modified BCLC B sub-classification and dispersion of tumour to show that surgical resection may be curative in a select subgroup of patients with intermediate HCC that fall outside BCLC Stage A, specifically those with unilobar lesions and are within the “up-to-7” criteria. Furthermore, We found that size prognosticates resection outcomes in solitary tumours.

Abstract
In this paper we describe the Kottamia Faint Imaging Spectro-Polarimeter (KFISP) that has been recently developed and designed to be mounted at the Cassegrain focus of the 1.88 m telescope at Kottamia Astronomical Observatory (KAO), Egypt. The optical design of KFISP is developed such that it can be used in various modes of operation. These are: direct imaging, spectroscopic, polarimetric imaging, and spectro-polarimetric. The KFISP is an all-refractive design to meet the polarimetric requirements and includes a focal reducer with a corrector section, collimator section, parallel beam section (containing various imaging components), and camera section. The corrector section gives an unvignetted Field-of-View of 8' × 8' and the collimator section has a focal length of 305 mm and matches the focal ratio of the input beam. The parallel beam section is 200 mm long and near the middle of it there is an image of the telescope pupil. The camera section includes 5 elements and has a focal length of 154.51 mm which gives an instrument effective final focal ratio of f/6.14 (acting as a telescope focal reducer of 1:2 ratio). The KFISP contains an internal calibration system which hosts the calibration light injection system, an integrating sphere equipped with the required calibration light sources. The opto-mechanical parts of KFISP contain a double-layered carbon fiber strut structure and comprises its subsystems of slit and guider assemblies, filter wheel drawer, grism wheel drawer, polarimetric components cubical box, and CCD camera which is integrated with camera optics. The CCD camera has 2048 × 2048 pixels with 13.5-micron square pixel size. The camera is cooled by liquid Nitrogen and is fixed to the KFISP through the integrated camera lens. The KFISP has been fully commissioned, mounted and is being tested in all modes of operation. In this paper we introduce the ambitious scientific goals, the optical setups of KFISP, its opto-mechanical implementation and the performance analysis of the instrument. In addition, we describe the camera system, its performance, and its software control. Finally, we present a sample of the first light observations obtained from the instrument.

Abstract
Metered dose inhalers (MDIs) are one of the most common device types for delivering inhaled therapies. However, there are several technical challenges in development and drug delivery of these medications. In particular, suspension-based MDIs are susceptible to suspension heterogeneity, in vitro drug–drug interactions, and patient handling errors, which may all affect drug delivery. To overcome these challenges, new formulation approaches are required. The AerosphereTM inhaler, formulated using co-suspension delivery technology, combines drug crystals with porous phospholipid particles to create stable, homogenous suspensions that dissolve once they reach the airways. Two combination therapies using this technology have been developed for the treatment of COPD: glycopyrrolate/formoterol fumarate (GFF MDI; dual combination) and budesonide/glycopyrrolate/formoterol fumarate (BGF MDI; triple combination). Here, we review the evidence with a focus on studies assessing dose delivery, lung deposition, and effects on airway geometry. In vitro assessments have demonstrated that the Aerosphere inhaler provides consistent dose delivery, even in the presence of simulated patient handling errors. Combination therapies delivered with this technology also show a consistent fine particle fraction (FPF) and an optimal particle size distribution for delivery to the central and peripheral airways even when multiple drugs are delivered via the same inhaler. Studies using gamma scintigraphy and functional respiratory imaging have demonstrated that GFF MDI is effectively deposited in the central and peripheral airways, and provides clinically meaningful benefits on airway volume and resistance throughout the lung. Overall, studies suggest that the Aerosphere inhaler, formulated using co-suspension delivery technology, may offer advantages over traditional formulations, including consistent delivery of multiple components across patient handling conditions, optimal particle size and FPF, and effective delivery to the central and peripheral airways. Future studies may provide additional evidence to further characterize the clinical benefits of these technical improvements in MDI drug delivery.

Abstract
Background: GFF MDI is a glycopyrrolate/formoterol fumarate fixed-dose combination metered dose inhaler formulated using co-suspension delivery technology. This open-label, single-arm multicenter study (NCT02268396) evaluated the accuracy, reliability, and functionality of the GFF MDI AeroCount® dose indicator when used by patients with chronic obstructive pulmonary disease (COPD). Patients and Methods: The study enrolled subjects (40–80 years of age) with an established clinical history (≥6 months) of COPD, who completed an electronic diary twice daily to record study-drug administration time, the number of actuations used, and pre- and post-dose dose indicator readings. The primary endpoint was the percentage of devices for which the number of subject-reported actuations was consistent (±20 actuations) with the dose indicator-based actuation count (equal to 130 minus the dose indicator reading) at the end of the treatment period (4 weeks). Safety was monitored throughout the study. Results: A total of 138 subjects with moderate-to-very severe COPD (50.7% male; mean [standard deviation (SD)] age 62.1 [8.3] years) were enrolled and treated. Subject-reported actuation count and dose indicator-based actuation counts were consistent for 96.4% (132/137) of devices at the end of the treatment period (4 weeks) in the intent-to-treat (ITT) population and for all devices in the per-protocol (PP) population. The mean (SD) dose indicator-based actuation and subject-reported actuation counts in the ITT population (n = 137) were 113.4 (18.9) and 117.0 (19.0), respectively, with a mean (SD) difference of 3.6 (7.9). The mean (SD) dose indicator-based actuation and subject-reported actuation counts in the PP population (n = 112) were 116.8 (8.7) and 119.7 (8.1), respectively. There were no unexpected safety findings. Conclusions: This study supported the accuracy, reliability, and utility of the dose indicator integrated into the GFF MDI device when used by patients with COPD.

Abstract
To ensure consistency of clinical outcomes, orally inhaled therapies must exhibit consistent delivered dose and aerosol properties at the time of manufacturing, throughout storage, and during various patient-use conditions. Achieving consistency across these scenarios has presented a significant challenge, especially for combination products that contain more than one drug. This study characterized the delivered dose and aerosol properties of glycopyrrolate/formoterol fumarate metered dose inhaler (GFF MDI; Bevespi Aerosphere™). GFF MDI, a fixed-dose combination (FDC) of a long-acting muscarinic antagonist, glycopyrrolate (18 μg, equivalent to glycopyrronium 14.4 μg), and a long-acting β2-agonist, formoterol fumarate (9.6 μg; equivalent to formoterol fumarate dihydrate 10 μg), is formulated using innovative co-suspension delivery technology, which suspends micronized drug crystals with spray-dried phospholipid porous particles in hydrofluoroalkane propellant. In this study, delivered dose uniformity was assessed through the labeled number of doses, and aerosol properties, such as percent fine particle fraction (FPF) and mass median aerodynamic diameter, were determined by cascade impaction. GFF MDI achieved reproducible dose delivery and an FPF greater than 55%, whether formulated and delivered as a monocomponent or dual FDC. The performance of GFF MDI was maintained across various manufacturing batches, under extended storage, and with variations in flow rate. Furthermore, unlike a GFF drug crystal-only suspension, drug delivery remained consistent for GFF MDI when simulated patient-handling errors were applied, such as reduced shake energy and delays between shaking and actuation. These results demonstrate that co-suspension delivery technology overcomes well-known sources of variability in MDI drug delivery.

Abstract
Age estimation in the juvenile skeleton primarily relies on the assessment of the degree of dental and skeletal development relative to full maturity. The timing of the mineralization and eruption of the teeth is a sequential process that, compared to skeletal growth and development, is less affected by extrinsic influences such as nutrition and/or chronic illness. Accordingly, radiographic visualization and analysis of different tooth formation stages are the foundation for a number of widely applied age estimation standards. Presently, however, there is a relative paucity of contemporary dental age estimation standards for a Western Australian population. To that end, the aim of the present study is to develop statistically quantified radiographic age estimation standards for a Western Australian juvenile population. A total of 392 digital orthopantomograms (202 male and 190 female) of Western Australian individuals are analyzed. Following, Moorrees et al. (J. Dent. Res. 42 (1963a) 490-502; Am. J. Phys. Anthropol. 21 (1963) 205-213), dental development and root resorption was assessed. Alveolar eruption was analyzed following Bengston (Northwest Univ. Bull. 35 (1935) 3-9). Stages of dental development were used to formulate a series of age estimation polynomial regression models; prediction accuracy (±0.998 to 2.183 years) is further validated using a cross-validation (holdout) sample of 30 film orthopantomograms. A visual atlas of dental development and eruption was subsequently designed for the pooled sex sample. The standards presented here represent a non-invasive and statistically quantified approach for accurate dental age estimation in Western Australian juvenile individuals.

Abstract
Abstract
Background: Preclinical models have generally proven suboptimal for directing clinical application of new anti-cancer therapies. Here we detail an integrated research platform engaging core resources at JAX-WEST and the clinical research and genomics facilities at UCDCCC. Pilot studies using this platform are focusing on non-small cell lung cancer (NSCLC) due to molecular targets of interest, such as epidermal growth factor receptor (EGFR), heterogeneity in NSCLC tumor biology and the complexity of related cancer signaling pathways.
Methods: Clinically and demographically annotated cancer patients (pt) seen at UCDCCC and collaborating facilities undergo tumor biopsy of various types which are implanted into JAX Nod Scid Gamma (NSG) mice to develop PDXs. Pt tumors and subsequent PDXs are assessed by histomorphology, clinically applicable molecular biomarkers, gene expression arrays and genome-wide technologies (NGS). NSCLC PDXs are grouped as panels (EGFR mutant (MT), KRAS MT ALK+). PDX panels of interest undergo multi-regimen drug testing for differential efficacy, together with pre- and post-therapy NGS and timed tumor pharmacodynamics (PD) assessment, to determine mechanisms of primary and acquired resistance in individual PDX models and how to overcome them.
Results: As of November 2013 over 1,200 cancer pt tumors have been xenotransplanted into NSG mice (~175 from NSCLC), including successful PDX formation from small FNA and, cell pellets and transportability of specimens by overnight shipping for implantation. NSCLC PDXs show excellent histomorphologic, gene expression and mutational fidelity to host pt tumors, including mutation status for KRAS, EGFR and gene expression levels. Pilot studies in a panel of EGFR MT PDXs with TKI-acquired resistance demonstrate differential drug activity which mimics that of the host pt to the same therapy, and tumor PD at baseline and timed intervals post-therapy provide the basis for subgrouping resistance mechanisms
Conclusion: This UCDCCC-JAX collaboration has established a large resource applicable to multi-drug testing and tumor PD in a wide range of clinically and genomically characterized tumors, including PDX panels for representative oncogene-driven NSCLCs. An EGFR-directed pilot project supports the feasibility of systematically integrating data derived from these models in order to optimize drug development and treatment strategies to address drug resistance mechanisms. This approach to PDX development and testing will be prospectively integrated into a developing multi-institution clinical trial of the Southwest Oncology Group (S1403), designed to advance understanding of differences in inter- and intra-patient tumor biology and hasten the transition to personalized cancer therapy.

Abstract
Glutathione S-transferases (EC.2.5.1.18, GSTs) were purified from rat liver by S-hexylglutathione affinity chromatography and six isoforms, namely C-1, C-2, C-3, C-4, A-2 and A-1, were isolated by CM-cellulose and DEAE-cellulose ion-exchange columns. Tannic acid and butein showed varying degrees of inhibition on the six individual GST isoforms. When 1-chloro-2,4-dinitrobenzene (CDNB) was used as a substrate, butein exerted significantly more potent inhibition on the cationic isoforms C-2, C-3 and C-4 with IC50 values of 6.8, 8.5 and 8.0 muM respectively. All the isoforms showed lower activity towards p-nitrobenzyt chloride when compared to CDNB and inhibition of the p-nitrobenzyl chloride-activity by tannic acid and butein was also weaker. The inhibitory effects of tannic acid and butein on each isoform decreased generally with increasing pH in the range of 6.0 to 8.0. The optimum pHs for inhibitions by tannic acid and butein on the six individual isoforms lie in the pH range of 6.0 to 6.5.

Abstract
We report on a search for the standard-model Higgs boson in pp collisions at square root(s) = 1.96 TeV using an integrated luminosity of 2.0 fb(-1). We look for production of the Higgs boson decaying to a pair of bottom quarks in association with a vector boson V (W or Z) decaying to quarks, resulting in a four-jet final state. Two of the jets are required to have secondary vertices consistent with B-hadron decays. We set the first 95% confidence level upper limit on the VH production cross section with V(--> qq/qq')H(--> bb) decay for Higgs boson masses of 100-150 GeV/c2 using data from run II at the Fermilab Tevatron. For m(H) = 120 GeV/c2, we exclude cross sections larger than 38 times the standard-model prediction.

Abstract
A combined mass and particle identification fit is used to make the first observation of the decay B(s)(0) --> D(s)(+/-)K(-/+) and measure the branching fraction of B(s)(0) --> D(s)(+/-)K(-/+) relative to B(s)(0) --> D(s)(+)pi(-). This analysis uses 1.2 fb(-1) integrated luminosity of pp collisions at square root(s) = 1.96 TeV collected with the CDF II detector at the Fermilab Tevatron collider. We observe a B(s)(0) --> D(s)(+/-)K(-/+) signal with a statistical significance of 8.1 sigma and measure B(B(s)(0) --> D(s)(+/-)K(-/+) /B(B(s)(0) --> D(s)(+)pi(-) 0.097+/-0.018(stat) +/- 0.009(syst).

Abstract
5143 Background: IL-6 facilitates cancer cell survival via pleiotrophic effects on proliferation, apoptosis, angiogenesis, differentiation, and chemo-resistance. A multicenter phase II study of CNTO328 in chemo pretreated CRPC pts was conducted. Methods: Eligible pts had one prior chemotherapy, Zubrod performance status 0–2, and adequate end-organ function. Regimen: CNTO328 6 mg/kg IV q2 weeks x 12 cycles. Response assessment was q6 weeks. Primary endpoint was PSA response rate (RR) defined as ≥50% reduction. Accrual was completed in 2 stages, with planned accrual of 20 eligible pts in the first stage and 40 overall. Plasma cytokines were measured by Luminex in 44 pts. Results: Of 62 pts, 54 were eligible; all had received prior taxane therapy. Two (3.7%; 95% CI: 0.5%, 12.8%) had PSA response. Of 47 pts evaluable by RECIST, none had a response and 10 (21%) had stable disease (SD). With median follow-up of 6.6 months, median progression-free survival is 1.6 months (95% CI: 1.6, 1.7). Grade 4 toxicity included 1 case of DIC and 1 CNS ischemia; grade 3 toxicities included elevated AST (1), gastritis/esophagitis (2), thrombocytopenia (2), pain (2), leucopenia (1), and neuropathy (2). Median baseline IL-6 levels were 12.5 pg/mL (IQR: 2.5, 41.5). Pts with levels >12.5 pg/mL had worse 6-month survival vs. < 12.5 pg/mL (53% vs 94%, p = 0.02). Post-cycle 1, IL-6 levels were > 250-fold higher, indicating antibody-target complex formation. 33/39 pts had a decline in C-reactive protein (CRP) plasma levels at 6 weeks. Conclusions: CNTO328 was well-tolerated and resulted in a PSA RR of 3.7% and RECIST SD rate of 21%. Declining CRP levels during treatment reflect biologic activity. Elevated baseline IL-6 levels portend a poor prognosis. Additional translational studies will be presented. Additional study of CNTO328 in combination may be warranted. [Table: see text]

Abstract
11076 Background: High EGFR gene copy number is associated with efficacy in NSCLC patients (pts) receiving combined chemotherapy and cetuximab (S0342). EGFR protein is typically overexpressed in tumors with high copy number but no consistent association has yet been demonstrated between EGFR protein expression and outcome in pts treated with chemotherapy plus cetuximab. EMT is associated with aggressive biological behavior and resistance to anti-EGFR TKI therapy in NSCLC. Our objective was to identify any association between EGFR protein and EMT and to correlate findings with pt outcomes from cetuximab/chemotherapy in SWOG trials S0342 (paclitaxel [P]-carboplatin [CB] plus sequential or concurrent cetuximab [CX]) and S0536 (P-CB-CX + bevacizumab). Methods: Paraffin sections were stained by immunoperoxidase methods using monoclonal antibodies against EGFR and the EMT markers vimentin, E-cadherin and Zeb1. Sections were scored on continuous scale ranging from 0–300 based on the H score (sum of % positive at each intensity from 0–3). Results were compared to outcome by Kaplan-Meier plot. Results: 79 samples from S0342 were evaluated for EGFR and EMT markers. 67 samples from S0536 were assessed for EGFR only. Mean EGFR H score was 153 and 137 for S0342 and S0536 respectively. At all cut points tested (scores 0, <100, <300) no association between EGFR H score and response or progression-free survival (PFS) was detected in either trial. There was a trend for overall survival and EGFR level at each cutpoint in S0536 but the results did not achieve statistical significance (15 vs 11 mos, p=0.14; 15 vs 11 mos, p=0.20 and 14 mos vs not reached, p=0.10, respectively). Vimentin (6 positive pts) was associated with a shorter PFS, HR=2.60 (1.10–6.14), p=0.03. ECAD and Vimentin were significantly inversely correlated with one another (Spearman p-value<0.01) Conclusions: EGFR protein level by IHC does not significantly correlate with efficacy parameters in chemotherapy/cetuximab-treated NSCLC pts. Patients with vimentin producing tumors (and possible other EMT markers) had shorter PFS, suggesting possible relative resistance to EGFR blockade from cetuximab. [Table: see text]

Abstract
2543 Background: DNA damage is the critical step in cancer cell response to platinum (Pt) chemotherapy. We hypothesize that low levels of Pt-induced DNA damage are predictive of chemoresistance. Accelerator mass spectrometry (AMS), an ultrasensitive method for measuring radiocarbon, can detect [14C]carboplatin bound to the DNA of cancer cells from cell culture, mice bearing tumor xenografts and patients receiving subtoxic microdoses of compound. Methods: Cancer cells and mice bearing tumor xenografts were treated with one microdose (1/100th of the therapeutic dose) or one therapeutic dose of [14C]carboplatin. Relevant parameters such as drug influx/efflux, intracellular drug inactivation, DNA damage and repair, were measured and correlated with response to chemotherapy. A Phase 0 microdosing trial has been designed to study patients with non-small cell lung or bladder transitional cell cancers who are planning to receive Pt-based chemotherapy. One microdose of [14C]carboplatin is administered to these patients 4 hours before biopsy. Pt-induced DNA damage and repair in tumor biopsy specimens and other relevant parameters will be measured and correlated with the response and toxicity of chemotherapy. Results: Preclinical studies showed that AMS can detect Pt-DNA damage when cancer cells and mice with tumor xenografts are exposed to one microdose of [14C]carboplatin. The levels of microdose-induced DNA damage are directly proportional to the damage caused by a therapeutic drug dose (p<0.001); and these levels of DNA damage correlate with chemoresistance as measured by MTT assay. Measuring drug uptake/efflux and intracellular inactivation allows insights into resistance mechanisms. These data support the conclusion that the levels of DNA damage induced by microdosing can potentially predict chemoresistance in patients. Consequently, a Phase 0 microdosing trial is in progress. Conclusions: These results support a phase 0 microdosing trial employing AMS to identify chemoresistance and determine the underlying chemoresistant mechanisms for personalized therapy before patients receive cytotoxic chemotherapy.

Abstract
We report a measurement of the top-quark mass M_{t} in the dilepton decay channel tt[over ] --> bl;{'+} nu_{l};{'}b[over ]l;{-}nu[over ]_{l}. Events are selected with a neural network which has been directly optimized for statistical precision in top-quark mass using neuroevolution, a technique modeled on biological evolution. The top-quark mass is extracted from per-event probability densities that are formed by the convolution of leading order matrix elements and detector resolution functions. The joint probability is the product of the probability densities from 344 candidate events in 2.0 fb;{-1} of pp[over ] collisions collected with the CDF II detector, yielding a measurement of M_{t} = 171.2 +/- 2.7(stat) +/- 2.9(syst) GeV / c;{2}.

Abstract
We present the first direct experimental bound on the total decay width of the top quark, Gamma(t), using 955 pb(-1) of the Tevatron's pp collisions recorded by the Collider Detector at Fermilab. We identify 253 top-antitop pair candidate events. The distribution of reconstructed top quark mass from these events is fitted to templates representing different values of the top quark width. Using a confidence interval based on likelihood-ratio ordering, we extract an upper limit at 95% C.L. of Gamma(t)<13.1 GeV for an assumed top quark mass of 175 GeV/c(2).

Abstract
Models of maximal flavor violation (MxFV) in elementary particle physics may contain at least one new scalar SU(2) doublet field Phi(FV)=(eta(0),eta(+)) that couples the first and third generation quarks (q_(1), q_(3)) via a Lagrangian term L(FV)=xi(13)Phi(FV)q(1)q(3). These models have a distinctive signature of same-charge top-quark pairs and evade flavor-changing limits from meson mixing measurements. Data corresponding to 2 fb(-1) collected by the Collider Dectector at Fermilab II detector in pp[over ] collisions at sqrt[s]=1.96 TeV are analyzed for evidence of the MxFV signature. For a neutral scalar eta(0) with m_(eta;(0))=200 GeV/c(2) and coupling xi(13)=1, approximately 11 signal events are expected over a background of 2.1+/-1.8 events. Three events are observed in the data, consistent with background expectations, and limits are set on the coupling xi(13) for m(eta(0)=180-300 GeV/c(2).

Abstract
We report a measurement of the single-top-quark production cross section in 2.2 fb;{-1} of pp collision data collected by the Collider Detector at Fermilab at sqrt[s]=1.96 TeV. Candidate events are classified as signal-like by three parallel analyses which use likelihood, matrix element, and neural network discriminants. These results are combined in order to improve the sensitivity. We observe a signal consistent with the standard model prediction, but inconsistent with the background-only model by 3.7 standard deviations with a median expected sensitivity of 4.9 standard deviations. We measure a cross section of 2.2(-0.6)(+0.7)(stat+syst) pb, extract the Cabibbo-Kobayashi-Maskawa matrix-element value |V(tb)|=0.88(-0.12)(+0.13)(stat+syst)+/-0.07(theory), and set the limit |V(tb)|>0.66 at the 95% C.L.

Abstract
We use the three lepton and missing energy trilepton signature to search for chargino-neutralino production with 2.0 fb;{-1} of integrated luminosity collected by the CDF II experiment at the Tevatron pp[over ] collider. We expect an excess of approximately 11 supersymmetric events for a choice of parameters of the mSUGRA model, but our observation of 7 events is consistent with the standard model expectation of 6.4 events. We constrain the mSUGRA model of supersymmetry and rule out chargino masses up to 145 GeV/c;{2} for a specific choice of parameters.

Abstract
We present a search for the Higgs boson in the process qq-->ZH-->l;{+}l;{-}bb[over ]. The analysis uses an integrated luminosity of 1 fb;{-1} of pp[over ] collisions produced at sqrt[s]=1.96 TeV and accumulated by the upgraded Collider Detector at Fermilab (CDF II). We employ artificial neural networks both to correct jets mismeasured in the calorimeter and to distinguish the signal kinematic distributions from those of the background. We see no evidence for Higgs boson production, and set 95% C.L. upper limits on sigma{ZH}B(H-->bb[over ]), ranging from 1.5 to 1.2 pb for a Higgs boson mass (m{H}) of 110 to 150 GeV/c(2).

Abstract
We present measurements of the forward-backward charge asymmetry in top pair production using 1.9 fb;{-1} of pp[over ] collisions at sqrt[s]=1.96 TeV recorded with the Collider Detector at Fermilab II. Correcting for acceptance and measurement dilutions we obtain parton-level asymmetries of A_{FB};{pp[over ]}=0.17+/-0.08 in the pp[over ] frame and A_{FB};{tt[over ]}=0.24+/-0.14 in the tt[over ] frame. The values are consistent with the standard model expectation and disfavor exotic production mechanisms with significant negative values.

Abstract
We report a search for the flavor-changing neutral-current decay of the top quark t-->Zq (q=u, c) in pp collisions at sqrt[s]=1.96 TeV using a data sample corresponding to an integrated luminosity of 1.9 fb(-1) collected by the CDF II detector. This decay is strongly suppressed in the standard model and an observation of a signal at the Fermilab Tevatron would be an indication of physics beyond the standard model. Using Z+ > or = 4 jet final state candidate events, with and without an identified bottom quark jet, we obtain an upper limit of B(t-->Zq) < 3.7% at 95% C.L.

Abstract
We present the results of searches for large extra dimensions in samples of events with large missing transverse energy E_{T} and either a photon or a jet produced in pp[over ] collisions at sqrt[s]=1.96 TeV collected with the Collider Detector at Fermilab II. For gamma+E_{T} and jet+E_{T} candidate samples corresponding to 2.0 and 1.1 fb;{-1} of integrated luminosity, respectively, we observe good agreement with standard model expectations and obtain a combined lower limit on the fundamental parameter of the large extra dimensions model M_{D} as a function of the number of extra dimensions in the model.

Abstract
We search for pair production of doubly charged Higgs particles (H+/- +/-) followed by decays into electron-tau (etau) and muon-tau (mutau) pairs using data (350 pb(-1) collected from [over]pp collisions at sqrt[s]=1.96 TeV by the CDF II experiment. We search separately for cases where three or four final-state leptons are detected, and combine results for exclusive decays to left-handed etau (mutau) pairs. We set an H+/- +/- lower mass limit of 114(112) GeV/c(2) at the 95% confidence level.

Abstract
We search for pair production of supersymmetric top quarks (t over1), followed by R-parity violating decay t over1-->taub with a branching ratio beta, using 322 pb(-1) of pp over collisions at sqrt s=1.96 TeV collected by the upgraded Collider Detector at Fermilab. Two candidate events pass our final selection criteria, consistent with the standard model expectation. We set upper limits on the cross section sigma(t over1t over1) x beta2 as a function of the top-squark mass m(t over1). Assuming beta=1, we set a 95% confidence level limit m(t over1)>153 GeV/c2. The limits are also applicable to the case of a third-generation scalar leptoquark (LQ3) decaying LQ3-->taub.

Abstract
We report on a search for narrow-width particles decaying to a top and antitop quark pair. The data set used in the analysis corresponds to an integrated luminosity of 680 pb(-1) collected with the Collider Detector at Fermilab in run II. We present 95% confidence level upper limits on the cross section times branching ratio. Assuming a specific top-color-assisted technicolor production model, the leptophobic Z' with width Gamma(Z')=0.012M(Z'), we exclude the mass range M(Z')<725 GeV/c(2) at the 95% confidence level.

Abstract
We search for the standard model Higgs boson produced in association with an electroweak vector boson in events with no identified charged leptons, large imbalance in transverse momentum, and two jets where at least one contains a secondary vertex consistent with the decay of b hadrons. We use approximately 1 fb(-1) integrated luminosity of pp collisions at square root(s)=1.96 TeV recorded by the Collider Detector at Fermilab II experiment at the Tevatron. We find 268 (16) single (double) b-tagged candidate events, where 248+/-43 (14.4+/-2.7) are expected from standard model background processes. We observe no significant excess over the expected background and thus set 95% confidence level upper limits on the Higgs boson production cross section for several Higgs boson masses ranging from 110 to 140 GeV/c(2). For a mass of 115 GeV/c(2), the observed (expected) limit is 20.4 (14.2) times the standard model prediction.

Abstract
We report the first evidence of Z boson pair production at a hadron collider with a significance exceeding 4 standard deviations. This result is based on a data sample corresponding to 1.9 fb(-1) of integrated luminosity from pp[over] collisions at sqrt[s]=1.96 TeV collected with the Collider Detector at Fermilab II detector. In the lll'l' channel, we observe three ZZ candidates with an expected background of 0.096(-0.063)+0.092 events. In the llnunu channel, we use a leading-order calculation of the relative ZZ and WW event probabilities to discriminate between signal and background. In the combination of lll'l' and llnunu channels, we observe an excess of events with a probability of 5.1 x 10(-6) to be due to the expected background. This corresponds to a significance of 4.4 standard deviations. The measured cross section is sigma(pp[over]-->ZZ)=1.4(-0.6)+0.7(stat+syst) pb, consistent with the standard model expectation.
