1. Clinical case of gusher-syndrome in surgery of a congenital isolated malformation of the middle ear

Author: Svetlana V. Astashchenko, Igor А. Anikin, Sergei N. Ilyin, Oleg I. Goncharov, Denis D. Kaliapin, Ilya M. Dyakov, and Anastasiya A. Valkova
Subjects: surgery of the stapes, ankylosis of the stapes, gusher syndrome, isolated middle ear malformation, Medicine (General), R5-920, Therapeutics. Pharmacology, RM1-950
Abstract: Gusher syndrome is a rather rare condition complicating surgical interventions on the stapes. It is characterized by profuse effusion of perilymphatic fluid from the vestibule into the lumen of the tympanic cavity during fenestration or removal of the foot plate of the stapes and rapid filling of the volume of the tympanic cavity and the external auditory canal with perilymph. This is due to increased pressure of perilymph fluid in the inner ear cavity in some developmental anomalies. Preoperative diagnosis of gusher syndrome can be difficult when the CT scan does not show any abnormalities in the anatomy of the inner ear canal and inner ear structures. The rarity of this phenomenon greatly complicates the procedure of its study, as well as the development of optimal schemes of therapeutic and diagnostic tactics in a real clinical situation. A clinical case of a combination of congenital isolated middle ear developmental anomaly and gusher syndrome is studied. A patient with suspected otosclerosis underwent stapedoplasty at Saint-Petersburg Research Institute of Ear, Throat, Nose and Speech. During the operation, abundant perilymphorrhea "Gusher" symptom was obtained, as well as thickening of the stapes legs and thin tendon of the stirrup muscle were revealed. The postoperative diagnosis was changed from otosclerosis to congenital isolated anomaly of middle ear development (isolated ankylosis of the stapes), gusher syndrome. The tactics of management of a patient with otosclerosis and isolated middle ear anomaly are similar. CT of temporal bones and virtual CT endoscopy should become the standard of examination of patients before surgical treatment. The use of cartilage and supracartilage is a safe way to stop perilymphorrhea in patients with gusher syndrome.

Subjects: bladder cancer, human papillomavirus, urothelial carcinoma, transurethral resection of the bladder, Neoplasms. Tumors. Oncology. Including cancer and carcinogens, RC254-282
Abstract: Purpose of the study. To study the histological type, grade of tumor differentiation in patients with primary and recurrent clinically non-muscle-invasive bladder cancer (NMIBC) with highly carcinogenic human papillomavirus (HPV) infection.Patients and methods. Formalin-fixed and paraffin-embedded bladder tumor tissue samples have been studied in 159 patients who underwent transurethral resection (TUR) of the bladder, for the presence of HPV DNA. To detect, quantify and differentiate DNA of HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68 genotypes in the samples, the AmpliSense® HPV HRC genotype-titer-FL was used. The result of the study was taken into account when the amount of DNA of the β-globin gene was at least 1000 copies per reaction. In order to statistically analyze our data we used the Fisher exact test and also calculated the odds ratio (OR) and 95 % CI.Results. According to the results of the study, out of 159 patients, high-risk HPV DNA was detected in the tumor tissue in 59 (37.1 %), of which HPV type 16 was found in 52 patients (89.4 %), HPV 18 was detected in 4 patients type (6.7 %) and type 35 in 3 (5.08 %). In a morphological study of the tissues of HPV-positive patients, the grade of tumor differentiation was G2 in 18 cases (30.5 %), G3 in 37 blocks, and G1 was detected only in 4 cases (6.7 %). In the presence of HPV, the chance of detecting a stage G3 tumor increases by 4.3 times. According to the received data, we can assume that there is a close relationship between detection in HPV patients of high-risk genotypes with moderately differentiated and low-differentiated forms of bladder cancer.Conclusion. this study may indicate that HPV infection affects the grade of tumor differentiation, and this, in turn, may allow the use of the HPV test to assess the nature of the development of relapse and/or progression of the disease.

3. Implementation of (λ, µ)-Convolution Product by Means of Tensordot Operation from Libraries for Tensor Algebra

Author: Evgeniy I. Goncharov
Subjects: multidimensional matrix algebra, (λ, µ)-convolution product, tensordot, numpy, cupy, pytorch, tensorflow, Electronic computers. Computer science, QA75.5-76.95
Abstract: Multidimensional matrix algebra is a successful data model for problems from a variety of subject areas. Many authors have described hardware and software complexes that implement the algebra of multidimensional matrices in its entirety or parallel algorithms of (λ, µ)-convolution product to solve a specific problem. Their implementation requires considerable labor, and the use of knowledge and installation of certain frameworks and compilers. Nevertheless, in the process of research, it is often useful to “test” the assumption on special cases, which may quickly give a counterexample. The article is devoted to the creation of such a tool for applied research. Python-programs are easy to write, thanks to the syntax, and have an extensive selection of various libraries. Among them, a special place is occupied by libraries for fast calculations: NumPy, CuPy, PyTorch, TensorFlow. They can provide sufficient computing speed on both CPU and GPU, and have significant functionality for working with multidimensional objects, although they do not implement a (λ, µ)-convolution product. The article shows that the operation (0, µ)-convolution product from the algebra of multidimensional matrices exactly coincides with the tensordot(A, B, µ) operation from python-libraries for tensor algebra. The article contains the results of an experiment comparing the calculation speed of this operation in different libraries. The author introduces a parallel algorithm for multiplying multidimensional matrices, reducing the (λ, µ)-convolution product to a sequence of (0, µ)-convolution products that can be performed in parallel. This actually reduces a complex task to a parallel call of the tensordot function. The article contains a detailed description of the program implementing the algorithm and the results of its testing in different runtime environments.

4. BILL OF LADING IN LEGAL REGULATION OF FOREIGN TRADE ACTIVITY: FROM PERSONAL SUBSCRIPTION TO ELECTRONIC CRYPTO CODE

Author: Agnessa O. Inshakova and Alexander I. Goncharov
Subjects: goods, foreign trade deal, transportation, sea ship, bill of lading, smart application, blockchain, Law
Abstract: Sea freight was and remains the most popular way of cargo delivery. Transportation of goods by sea routes plays a crucial role in the economy of most countries. The bill of lading acts as a legal instrument and guarantees the interests of participants in foreign trade deals and has a complex legal nature, due to its functionality. The use of electronic documents for formalizing relations between the participants in the maritime transport of goods has become possible due to the rapid development and widespread introduction of information technologies into the property turnover. In the period of digitalization of the Russian economy, the study of the legal regulation of the bill of lading accompanied by special computer software products is relevant and significant. The main purpose of the article is to disclose the essential characteristics of a bill of lading as a trading, title-bearing security from the perspective of the evolutionary development of this legal instrument over several centuries. The authors formulate a number of recommendations for the expanded implementation of electronic document circulation in maritime trade, arguing that, along with the adopted legal acts, should clarify the use of electronic documents when transporting goods by sea. In the Russian Federation, the rules on bills of lading must be supplemented by international agreements, additionally adopt a number of national legal acts in this sphere. The theoretical basis of the research was the studies of Russian and foreign investigators, which examine the relations of entities applying bills of lading in foreign economic activity (Vilkova, 2004; Golubchik, Katykha, 2017; Dubovec, 2006; Inshakova, Kalinina, Goncharov, 2019; Skaridov, 2018 et al.). Methodologically, the present research is based on the authors' materialistic worldview. General scientific methods were used: dialectic, inductive, deductive, analysis, synthesis, generalization, etc., as well as particular scientific methods: formal legal, comparative legal, etc.). As a result of the scientific analysis for the expanded implementation of electronic document circulation in maritime trade, along with the adopted legal acts, the authors proposed to specify the use of electronic documents for the carriage of goods by sea. The rules on bills of lading must be supplemented by international agreements, and a number of national legal acts in this area should be adopted. Suggestions for Smart applications to bills of lading and electronic registration of microchips, which should mark the goods moved by foreign trade deals, which will positively affect the increase of the rule of law at the domestic level through more precise electronic customs, tax, currency control. It is substantiated that in the aspect of the implementation of economic relations, digital registration acts a preventive and prophylactic function - reducing potential conflicts. To realize the benefits of smart applications to bills of lading, it is recommended to develop and adopt a set of legal norms of legislative and sub-legal level governing public relations in the digital economy, implementing these smart applications to bills of lading implementing business practice and inter-jurisdictional polysubject blockchain.

Abstract: AIM. To study the possibility of using a paired (test) H-reflex recovery test in the expert assessment of the intensity of acute pain syndromes and in the control of performed therapy. MATERIALS AND METHODS. The authors analyzed 40 patients treated for radicular pain syndrome (RPS) caused by disk protrusion or herniation at the lumbar spine with the pain intensity of up to 9 points on digital rank scale of pain. As a clinical model they used a pathogenetically sound therapeutic blockade method including glucocorticosteroids for the therapy of acute neuralgia and basic medical therapy with Arcoxia 120 mg/day. Investigations were conducted to study the specific features of early recovery of test H-reflex caused in pair with a conditioning H-reflex in both healthy volunteers and patients with obvious RPS. RESULTS. There were different features of paired H-reflex recovery in healthy individuals and patients with RPS during different treatment options. Recovery of test H-reflex in the range of 150-200 msec can be a criterion for a pain state. CONCLUSION. The clinical test reflex recovery technique may be used in the diagnosis and monitoring of the performed therapy of acute pain syndromes, as well as in the expert examination of pain states.

Abstract: Using data corresponding to an integrated luminosity of 79 pb-1, D0 has searched for events containing multiple jets and large missing transverse energy in pbar-p collisions at sqrt(s)=1.8 TeV at the Fermilab Tevatron collider. Observing no significant excess beyond what is expected from the standard model, we set limits on the masses of squarks and gluinos and on the model parameters m_0 and m_1/2, in the framework of the minimal low-energy supergravity models of supersymmetry. For tan(beta) = 2 and A_0 = 0, with mu < 0, we exclude all models with m_squark < 250 GeV/c^2. For models with equal squark and gluino masses, we exclude m < 260 GeV/c^2., 10 pages, 3 figures, Submitted to PRL, Fixed typo on page bottom of p. 6 (QCD multijet background is 35.4 events)

Abstract: Using the DO detector, we have observed events produced in (p) over barp collisions that contain W or Z bosons in conjunction with very little energy deposition ("rapidity gaps") in large forward regions of the detector. The fraction of W boson events with a rapidity gap (a signature for diffraction) is 0.89 +/- (0.19)(0.17)% and the probability that the non-diffractive background fluctuated to yield the observed diffractive signal is 3 x 10(-14), corresponding to a significance of 7.5 sigma. The Z boson sample has a gap fraction of 1.44 +/- (0.61)(0.52)%, with a significance of 4.4 sigma. The diffractive events have very similar properties to the more common non-diffractive component.

Abstract: We examine properties of ttbar candidates events in lepton+jets final states to establish the helicities of the W bosons in t->W+b decays. Our analysis is based on a direct calculation of a probability that each event corresponds to a ttbar final state, as a function of the helicity of the W boson. We use the 125 events/pb sample of data collected by the DO experiment during Run I of the Fermilab Tevatron collider at sqrt{s}=1.8 TeV, and obtain a longitudinal helicity fraction of F_0=0.56+/-0.31, which is consistent with the prediction of F_0=0.70 from the standard model.

Abstract: We present a measurement of the Drell-Yan cross section at high dielectron invariant mass using 120/pb of data collected in pbar-p collisions at sqrt(s) = 1.8 TeV by the D0 collaboration during 1992-96. No deviation from standard model expectations is observed. We use the data to set limits on the energy scale of quark-electron compositeness with common constituents. The 95% confidence level lower limits on the compositeness scale vary between 3.3 TeV and 6.1 TeV depending on the assumed form of the effective contact interaction., 6 pages, 2 figures, submitted to PRL

Abstract: We report a search for effects of large extra spatial dimensions in ppbar collisions at a center-of-mass energy of 1.8 TeV with the DZero detector, using events containing a pair of electrons or photons. The data are in good agreement with the expected background and do not exhibit evidence for large extra dimensions. We set the most restrictive lower limits to date, at the 95% confidence level, on the effective Planck scale between 1.0 TeV and 1.4 TeV for several formalisms and numbers of extra dimensions., Comment: 6 pages, 2 figures, submitted to Phys.

Abstract: The transverse single-spin asymmetry was measured for charged hadrons (π ±, K ±, p, $$\bar p$$ ) produced in proton-nucleus collisions. The measurements were performed at the FODS-2 spectrometer by using a polarized proton beam that was accelerated to an energy of 40 GeV at the accelerator of the Institute for High Energy Physics (IHEP, Protvino) and which was made to hit carbon and copper nuclear targets. The data in question were obtained in the range of c.m. angles between 73° and 94° near the central region (−0.01 < x F < 0.27, 0.7 < p T < 3.6 GeV/c). The single-spin asymmetry for π + and K + mesons is significant at high values of p T and moderately small positive values of x F. The analyzing power for other hadrons (π −, K −, p, $$\bar p$$ ) is compatible with zero in the p T range studied here. The dependence of the analyzing power on the mass number of the target nucleus is insignificant.

Abstract: The transverse single-spin asymmetry was measured for charged hadrons ({pi}{sup {+-}}, K{sup {+-}}, p, p-bar) produced in proton-nucleus collisions. The measurements were performed with the aid of the FODS-2 spectrometer by using a 40-GeV polarized proton beam from the accelerator of the Institute for High Energy Physics (IHEP, Protvino) and carbon and copper nuclear targets. The data subjected to the analysis in the present study were obtained for c.m. angles in the range 95{sup o}-112{sup o} in the vicinity of the central region (-0.08 < x{sub F} < -0.06, 0.7 < p{sub T} < 3.4 GeV/c). The analyzing power is found to be only slightly dependent on the mass number of the target nucleus. The basic results obtained by measuring the single-spin asymmetry at three values of the particle-detection angle are discussed.

Abstract: The transverse single-spin asymmetry for charged hadrons (π ±, K ±, p, $$\bar p$$ ) produced in proton-nucleus collisions was measured for c.m. production angles in the range 40°–79°. The measurements were performed with the FODS-2 setup by using a 40-GeV polarized proton beam originating from the accelerator of the Institute for High Energy Physics (Protvino) and hitting carbon and copper nuclear targets. The data in question were obtained in the polarized-proton-fragmentation region (0.0 < x F < 0.7, 0.6 < p T < 2.5 GeV/c). In agreement with data obtained at other energies, the single-spin asymmetry for π ± mesons is significant at high x F. For the first time, a sizable analyzing power, which changes sign at x F = 0.43, is observed for protons. The dependence of the analyzing power on the target-nucleus mass is insignificant.

Abstract: The production of noncoplanar hadron pairs in proton-nucleus interactions is studied experimentally for the case where the transverse momenta of product particles are in excess of 1 GeV/c. The values obtained for the exponent in the A dependence of the cross section for the production of noncoplanar hadron pairs are substantially greater than those for coplanar pairs. This nuclear-mass-number dependence for the production of hadron pairs can be explained by the contribution of multiparton interactions in proton-nucleus collisions.

Abstract: The characteristics of the prototype of the endcap hadron calorimeter for the CMS facility have been measured. Using the relations between the measured calorimeter response to a radiation source, muons, and pions, it is possible to determine the energy scale of the data-acquisition electronics, which will be used in future experiments along with the calorimeter. The light yield in the calorimeter due to a minimum-ionizing particle was measured. The effect of various factors on the duration of the calorimeter signal is analyzed. The joint operation of the hadron and electromagnetic calorimeters was investigated. The possibility of adjusting the uncompensated system using the data from a scintillation counter inserted between the calorimeters is analyzed. It is shown that the presence of a structural material between the calorimeters will not lead to a noticeable degradation in the energy resolution of the hadron calorimeter.

Abstract: We have searched for the signature of 3- and 4-body decays of pair-produced scalar top quarks (stop) in the inclusive final state containing an electron, a muon, and significant missing transverse energy using a sample of p p events corresponding to 108.3 pb−1 of data collected with the DO detector at Fermilab. The search is done in the framework of the minimal supersymmetric standard model assuming that the neutralino ( χ 0 1 ) is the lightest supersymmetric particle and is stable. No evidence for a signal is found and we derive cross-section upper limits as a function of stop (t) and neutralino masses in different decay scenarios leading to the blν χ 0 1 final state.

Abstract: Using the D empty set detector, we have studied events produced in (p) over barp collisions that contain large forward regions with very little energy deposition ("rapidity gaps") and concurrent jet production at center-of-mass energies of roots = 630 and 1800 GeV. The fraction of events with forward or central jets associated with rapidity gaps is compared to predictions for hard diffraction. We also extract the momentum loss for scattered protons in such processes. (C) 2002 Elsevier Science B.V. All rights reserved.

Abstract: We apply a quasi-model-independent strategy ("Sleuth") to search for new high p_T physics in approximately 100 pb^-1 of ppbar collisions at sqrt(s) = 1.8 TeV collected by the DZero experiment during 1992-1996 at the Fermilab Tevatron. We systematically analyze many exclusive final states and demonstrate sensitivity to a variety of models predicting new phenomena at the electroweak scale. No evidence of new high p_T physics is observed.

Abstract: We report on a study of the ratio of inclusive three-jet to inclusive two-jet production cross sections as a function of total transverse energy in p (p) over bar collisions at it center-of-mass energy roots = 1.8 TeV, using data collected with the DO detector during the 1992-1993 run of the Fermilab Tevatron Collider. The measurements are used to deduce preferred renormalization scales in perturbative O(alpha (3)(s)) QCD calculations in modeling soft-jet emission.

Abstract: We report a new measurement of the pseudorapidity (eta) and transverse-energy (Et) dependence of the inclusive jet production cross section in pbar b collisions at sqrt(s) = 1.8 TeV using 95 pb**-1 of data collected with the DZero detector at the Fermilab Tevatron. The differential cross section d^2sigma/dEt deta is presented up to |eta| = 3, significantly extending previous measurements. The results are in good overall agreement with next-to-leading order predictions from QCD and indicate a preference for certain parton distribution functions.

Abstract: Bottom quark production in pbar-p collisions at sqrt(s)=1.8 TeV is studied with 5 inverse picobarns of data collected in 1995 by the DO detector at the Fermilab Tevatron Collider. The differential production cross section for b jets in the central rapidity region (|y(b)| < 1) as a function of jet transverse energy is extracted from a muon-tagged jet sample. Within experimental and theoretical uncertainties, DO results are found to be higher than, but compatible with, next-to-leading-order QCD predictions.

Abstract: The D0 collaboration has performed a study of spin correlation in tt-bar production for the process tt-bar to bb-bar W^+W^-, where the W bosons decay to e-nu or mu-nu. A sample of six events was collected during an exposure of the D0 detector to an integrated luminosity of approximately 125 pb^-1 of sqrt{s}=1.8 TeV pp-bar collisions. The standard model (SM) predicts that the short lifetime of the top quark ensures the transmission of any spin information at production to the tt-bar decay products. The degree of spin correlation is characterized by a correlation coefficient k. We find that k>-0.25 at the 68% confidence level, in agreement with the SM prediction of k=0.88.

Abstract: of data collected with the DO detector during 1993-1995. We find that a(p (p) over bar --> W + X)B(W --> tau nu) = 2.22 +/- 0.09 (stat) +/- 0.10 (syst) +/- 0.10 (lum) nb. Lepton universality predicts that the ratio of the tau and electron electroweak charged current couplings to the W boson, g(T)(W)/g(e)(W), be unity. We find g(T)(W)/g(e)(W) = 0.980 +/- 0.031, in agreement with lepton universality.

Abstract: Inclusive dijet production at large pseudorapidity intervals (Delta eta) between the two jets has been suggested as a regime for observing Balitsky-Fadin-Kuraev-Lipatov (BFKL) dynamics. We have measured the dijet cross section for large Delta eta in p (p) over bar collisions at root s = 1800 and 630 GeV using the D0 detector. The partonic cross section increases strongly with the size of Delta eta; The observed growth is even stronger than expected on the basis of BFKL resummation in the leading logarithmic approximation. The growth of the partonic cross section can be accommodated with an effective BFKL intercept of alpha(BFKL)(20 GeV) = 1.65 +/- 0.07.

Abstract: This Letter describes a measurement of the muon cross section originating from b quark decay in the forward rapidity range 2.4 < y(mu) < 3.2 in pbarp collisions at sqrt(s) = 1.8 TeV. The data used in this analysis were collected by the D0 experiment at the Fermilab Tevatron. We find that NLO QCD calculations underestimate b quark production by a factor of four in the forward rapidity region. A cross section measurement using muon+jet data has been included in this version of the paper.

Abstract: We present a measurement of the transverse momentum distribution of Z bosons produced in ppbar collisions at sqrt{s}=1.8 TeV using data collected by the D0 experiment at the Fermilab Tevatron Collider during 1994--1996. We find good agreement between our data and a current resummation calculation. We also use our data to extract values of the non-perturbative parameters for a particular version of the resummation formalism, obtaining significantly more precise values than previous determinations.

Abstract: The monitoring system of the scintillation sandwich calorimeter is based on scintillator excitation by UV radiation. The system is composed of a nitrogen laser, neutral filters (7 stages of the laser-signal attenuation), and a set of laser-radiation distributors among the quartz fibers transmitting the light towards the scintillator tiles. The system is computer-controlled. A 780-channel system for monitoring the prototype calorimeter of the CMS setup was developed. The efficiency of the monitoring system was demonstrated by testing it on the accelerator beam. The error in measuring the amplitude of a laser-generated scintillation was 1%. The long-term stability of the system was characterized by a variance of 1.1%.

Abstract: We report on a search for second generation leptoquarks (LQ) produced in p (p) over bar collisions at root s = 1.8 TeV using the DO detector at Fermilab. Second generation leptoquarks are assumed to be produced in pairs and to decay to either mu. or nu and either a strange or a charm quark (q). Limits an placed on sigma(p (p) over bar --> LQ --> mu nu + jets) as a function of the mass of the leptoquark. For equal branching ratios to mu q and nu q, second generation scalar leptoquarks with a mass below 160 GeV/c(2), vector leptoquarks with anomalous minimal vector couplings with a mass below 240 GeV/c(2), and vector leptoquarks with Yang-Mills couplings with a mass below 290 GeV/c(2), are excluded at the 95% confidence level.

Abstract: Using the DZero detector at the 1.8 TeV pbarp Fermilab Tevatron collider, we have measured the inclusive dijet mass spectrum in the central pseudorapidity region |eta_jet| < 1.0 for dijet masses greater than 200 Gev/c^2. We have also measured the ratio of spectra sigma(|eta_jet| < 0.5)/sigma(0.5 < |eta_jet| < 1.0). The order alpha_s^3 QCD predictions are in good agreement with the data and we rule out models of quark compositeness with a contact interaction scale < 2.4 TeV at the 95% confidence level.

Abstract: We search for new physics using events with one high transverse energy photon, two or more jets, and an apparent imbalance in transverse energy, in p{ovr p} collisions at the Fermilab Tevatron at {radical} (s) =1.8 TeV . Such events are predicted for production of supersymmetric particles in some models. No excess is observed beyond expected background. For the parameter space of the minimal supersymmetric standard model with branching fraction B({tilde {chi}}{sup 0}{sub 2}{r_arrow}{gamma}thinsp{tilde {chi}}{sup 0}{sub 1})=1 and m{sub {tilde {chi}}{sup 0}{sub 2 }}{minus}m{sub {tilde {chi}}{sup 0}{sub 1}}{gt}20 GeV , we obtain a 95{percent} confidence level lower mass limit of 310thinspthinspGeV for equal mass squarks and gluinos. The results are also interpreted in models with low energy gauge mediated supersymmetry breaking. {copyright} {ital 1998} {ital The American Physical Society }

Abstract: We report on a search for $\mathrm{charge}\ensuremath{-}1/3$ third-generation leptoquarks (LQ) produced in $p\overline{p}$ collisions at $\ensuremath{\surd}s\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\mathrm{TeV}$ using the $\mathrm{D}0$ detector at Fermilab. Third-generation leptoquarks are assumed to be produced in pairs and to decay to a tau neutrino and a $b$ quark with branching fraction $B$. We place upper limits on $\ensuremath{\sigma}(p\overline{p}\ensuremath{\rightarrow}\mathrm{LQ}\overline{\mathrm{LQ}}){B}^{2}$ as a function of the leptoquark mass ${M}_{\mathrm{LQ}}$. Assuming $B\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$, we exclude at the 95% confidence level third-generation scalar leptoquarks with ${M}_{\mathrm{LQ}}l94\mathrm{GeV}{/c}^{2}$, and third-generation vector leptoquarks with ${M}_{\mathrm{LQ}}l216\mathrm{GeV}{/c}^{2}({M}_{\mathrm{LQ}}l148\mathrm{GeV}{/c}^{2}$) assuming Yang-Mills (anomalous) coupling.

Abstract: The shape of the transverse momentum distribution of W bosons (p_T(W)) produced in pbarp collisions at sqrt(s)= 1.8 TeV is measured with the DO detector at Fermilab. The result is compared to QCD perturbative and resummation calculations over the p_T(W) range from 0-200 GeV/c. The shape of the distribution is consistent with the theoretical prediction.

Abstract: We report a measurement of the W boson mass based on an integrated luminosity of 82 pb −1 from pp collisions at √s = 1.8 TeV recorded in 1994-1995 by the D0 detector at the Fermilab Tevatron. We identify W bosons by their decays to e∨ V and extract the mass by fitting the transverse mass spectrum from 28 323 W boson candidates. A sample of 3563 dielectron events, mostly due to Z→ee decays, constrains models of W boson production and the detector. We measure M W = 80.44±0.10(stat)±0.07(syst) GeV. By combining this measurement with our result form the 1992-1993 data set, we obtain M W = 80.43±0.11 GeV.

Abstract: We have searched for first generation scalar leptoquark (LQ) pairs in the enu+jets channel using ppbar collider data (integrated luminosity= 115 pb^-1) collected by the DZero experiment at the Fermilab Tevatron during 1992-96. The analysis yields no candidate events. We combine the results with those from the ee+jets and nunu+jets channels to obtain 95% confidence level (CL) upper limits on the LQ pair production cross section as a function of mass and of beta, the branching fraction to a charged lepton. Comparing with the next-to-leading order theory, we set 95% CL lower limits on the LQ mass of 225, 204, and 79 GeV/c^2 for beta=1, 1/2, and 0, respectively.
