description: A phase transition for bosonic atoms in a two-dimensional anisotropic optical lattice is considered. If the tunnelling rates in two directions are different, the system can undergo a transition between a two-dimensional superfluid and a one-dimensional Mott insulating array of strongly coupled tubes. The connection to other lattice models is exploited in order to better understand the phase transition. Critical properties are obtained using quantum Monte Carlo calculations. These critical properties are related to correlation properties of the bosons and a criterion for commensurate filling is established.

Groupthink in decision making : testing for its existence, effects and prevention
Creators: name: Kyle, Neil John
Publisher: name: University of British Columbia
Year: 2010

description: Groupthink is a theory concerning decision making developed by Janis (1972) on a case study basis. He uses the theory to explain several international fiascoes such as the Bay of Pigs invasion of Cuba. Highly cohesive, isolated groups operating in stressful circumstances, under highly assertive leaders may support the leader's position in the attempt to maintain group consensus. Experimental research reviewed by the present author is reinterpreted as not supporting the theory. Criticisms concerning the original development of the theory and the possibility of obtaining disconfirming evidence are outlined. The present experiment obtained for subjects 192 staff members from government and corporate organizations. Leadership style, cohesiveness and stress were manipulated to simulate the groupthink conditions. The four-person groups attempted to develop solutions to two current social problems: (1) Canadian immigration, and (2) capital punishment. The sessions were taperecorded and subjects were given post-experimental questionnaires. The questionnaires provided information for manipulation checks and the attempt to observe specific symptoms of groupthink. The audio-tapes were rated by two independent observers for the quality of the decision making discussions. The proposed solutions (in transcript form) were rated for their quality by experts from Immigration and law. Groupthink theory was not supported by the analyses at the various levels. The independent variable manipulations were moderately successful. The results indicated that leadership style played the dominant role in affecting both the group atmosphere and the quality of the decision making. These findings are interpreted as being consistent with earlier research on groupthink theory. It was also found that the time limitations employed in the study influenced the task oriented dimensions of the group processes It was suggested that the role of leadership may be more crucial to group-think theory than is the role of group cohesiveness. However, before reaching a decision on the validity of the groupthink theory based upon the current laboratory research, it is recommended that groupthink be tested in a fashion more appropriate to the level of analysis of the theory.

description: Butt rot (BR) damages associated with Norway spruce (Picea abies [L.] Karst.) account for considerable economic losses in timber production across the northern hemisphere. While information on BR damages is critical for optimal decision-making in forest management, the maps of BR damages are typically lacking in forest information systems. We predicted timber volume damaged by BR at the stand-level in Norway using harvester information of 186,026 stems (clear-cuts), remotely sensed, and environmental data (e.g. climate and terrain characteristics). We utilized random forest (RF) models with two sets of predictor variables: (1) predictor variables available after harvest (theoretical case) and (2) predictor variables available prior to harvest (mapping case). We found that forest attributes characterizing the maturity of forest, such as remote sensing-based height, harvested timber volume and quadratic mean diameter at breast height, were among the most important predictor variables. Remotely sensed predictor variables obtained from airborne laser scanning data and Sentinel-2 imagery were more important than the environmental variables. The theoretical case with a leave-stand-out cross-validation achieved an RMSE of 11.4 $m^3ha^{-1}$ (pseudo $R^2$: 0.66) whereas the mapping case resulted in a pseudo $R^2$ of 0.60. When the spatially distinct k-means clusters of harvested forest stands were used as units in the cross-validation, the RMSE value and pseudo $R^2$ associated with the mapping case were 15.6 $m^3ha^{-1}$ and 0.37, respectively. This indicates that the knowledge about the BR status of spatially close stands is of high importance for obtaining satisfactory error rates in the mapping of BR damages.

description: 25. Xyloryctidae – teardrop moths Small (12–18 mm wingspan) moths with narrow lanceolate wings. Most species have dark wings and rather wide bodies relative to those of other narrow-winged groups. Adults rest with the wings folded around the body in the shape of an elongate teardrop. Many species are diurnal. Th e larvae of most species construct webs from which they feed on leaves. A few species are miners. The family Xyloryctidae consists of approximately 1200 described species worldwide. Species richness is particularly notable in arid regions. Forty-two species are known in North America, all in the subfamily Scythridinae, which was considered a separate family before Hodges (1999a). Six species are known to occur in AB. The family was revised for North America by Landry (1991), who estimated that only 10% of Nearctic species had been described.

description: A recent sensitivity study has shown that the $^{35}$K$(p,γ)^{36}$Ca reaction is one of the ten $(p,γ)$ reaction rates that could significantly impact the shape of the calculated X-ray burst light curve. In this work, we propose to reinvestigate the $^{35}$K$(p,γ)^{36}$Ca reaction rate, as well as related uncertainties, by determining the energies and decay branching ratios of $^{36}$Ca levels, within the Gamow window, in the 0.5 to 2 GK X-ray burst temperature range. These properties were studied using the one neutron pick-up transfer reaction $^{37}$Ca$(p,d)^{36}$Ca in inverse kinematics using a radioactive beam of $^{37}$Ca at 48 MeV nucleon$^{-1}$. The experiment performed at GANIL, used the liquid Hydrogen target CRYPTA, the MUST2 detector array for the detection of the light charged particles and a zero degree detection system for the outgoing heavy ions. The atomic mass of $^{36}$Ca is confirmed and new resonances have been proposed together with their proton decay branching ratios. This spectroscopic information, used in combination with recent theoretical predictions for the $γ$-width, were used to calculate the $^{35}$K$(p,γ)^{36}$Ca reaction rate. The recommended rate of the present work was obtain within a uncertainty factor of 2 at 1 sigma. This is consistent, with the previous estimate in the X-ray burst temperature range. A large increase of the reaction rate was found at higher temperatures due to two newly discovered resonances. The $^{35}$K$(p,γ)^{36}$Ca thermonuclear reaction rate is now well constrained by the present work in a broad range of temperatures. Our results show that the $^{35}$K$(p,γ)^{36}$Ca reaction does not affect the shape of the X-ray burst light curve, and that it can be removed from the list of the few influential proton radiative captures reactions having a strong impact on the light curve.

The role of the Yarkovsky effect in the long-term dynamics of asteroid (469219) Kamo'oalewa

description: Near-Earth asteroid (469219) Kamo'oalewa (aka 2016 HO3) is an Earth co-orbital and a potential space mission target. Its short-term dynamics is characterized by a periodic switching between quasi-satellite and horseshoe configurations. Due to its small diameter of only about 36 meters, the Yarkovsky effect may play a significant role in the long-term dynamics. In this work, we addressed this issue by studying the changes in the long-term motion of Kamo'oalewa caused by the Yarkovsky effect. We used an estimation of the magnitude of the Yarkovsky effect assuming different surface compositions and introduced the semi-major axis drift by propagating orbits of test particles representing the clones of the nominal orbit. Our simulations showed that the Yarkovsky effect may cause Kamo'oalewa to exit from the Earth co-orbital region a bit faster when compared to a purely gravitational model. Nevertheless, it still could remain an Earth companion for at least 0.5 My in the future. Our results imply that Kamo'oalewa is the most stable Earth's co-orbital object known so far, not only from a short-term perspective but also on long time scales.

description: Extracting reliable low-energy information from string compactifications notoriously requires a detailed understanding of the UV sensitivity of the corresponding effective field theories. Despite past efforts in computing perturbative string corrections to the tree-level action, neither a systematic approach nor a unified framework has emerged yet. We make progress in this direction, focusing on the moduli dependence of perturbative corrections to the 4D scalar potential of type IIB Calabi-Yau orientifold compactifications. We proceed by employing two strategies. First, we use two rescaling symmetries of type IIB string theory to infer the dependence of any perturbative correction on both the dilaton and the Calabi-Yau volume. Second, we use F/M-theory duality to conclude that KK reductions on elliptically-fibred Calabi-Yau fourfolds of the M-theory action at any order in the derivative expansion can only generate $(α')^{\rm even}$ corrections to the 4D scalar potential, which, moreover, all vanish for trivial fibrations. We finally give evidence that $(α')^{\rm odd}$ effects arise from integrating out KK and winding modes on the elliptic fibration and argue that the leading no-scale breaking effects at string tree-level arise from $(α')^3$ effects, modulo potential logarithmic corrections.

description: In this paper we study the moduli space of representations of a surface group (i.e., the fundamental group of a closed oriented surface) in the real symplectic group Sp(2n,R). The moduli space is partitioned by an integer invariant, called the Toledo invariant. This invariant is bounded by a Milnor-Wood type inequality. Our main result is a count of the number of connected components of the moduli space of maximal representations, i.e. representations with maximal Toledo invariant. Our approach uses the non-abelian Hodge theory correspondence proved in a companion paper arXiv:0909.4487 [math.DG] to identify the space of representations with the moduli space of polystable Sp(2n,R)-Higgs bundles. A key step is provided by the discovery of new discrete invariants of maximal representations. These new invariants arise from an identification, in the maximal case, of the moduli space of Sp(2n,R)-Higgs bundles with a moduli space of twisted Higgs bundles for the group GL(n,R).

description: The ratio of the squares of the electric and magnetic proton form factors is shown to be proportional to the ratio of the cross sections for the elastic scattering of an unpolarized electron on a partially polarized proton with and without proton spin flip. The initial proton at rest should be polarized along the direction of the motion of the final proton. Similar results are valid for both radiative $ep$ scattering and the photoproduction of pairs on a proton in the Bethe--Heitler kinematics. When the initial proton is fully polarized in the direction of the motion of the final proton, the cross section for the $ep \to ep$ process, as well as for the $ep \to ep γ$ and $γp \to e \bar e p$ processes, without (with) proton spin flip is expressed only in terms of the square of the electric (magnetic) proton form factor. Such an experiment on the measurement of the cross sections without and with proton spin flip would make it possible to acquire new independent data on the behavior of $G_E^2(Q^2)$ and $G_M^2(Q^2)$, which are necessary for resolving the contradictions appearing after the experiment of the JLab collaboration on the measurement of the proton form factors with the method of polarization transfer from the initial electron to the final proton.

description: We consider estimating an unknown signal, both blocky and sparse, which is corrupted by additive noise. We study three interrelated least squares procedures and their asymptotic properties. The first procedure is the fused lasso, put forward by Friedman et al. [Ann. Appl. Statist. 1 (2007) 302--332], which we modify into a different estimator, called the fused adaptive lasso, with better properties. The other two estimators we discuss solve least squares problems on sieves; one constrains the maximal $\ell_1$ norm and the maximal total variation seminorm, and the other restricts the number of blocks and the number of nonzero coordinates of the signal. We derive conditions for the recovery of the true block partition and the true sparsity patterns by the fused lasso and the fused adaptive lasso, and we derive convergence rates for the sieve estimators, explicitly in terms of the constraining parameters.

description: We consider the motion of a spin-1/2 impurity in a one-dimensional gas of spin-1/2 fermions. For antiferromagnetic interaction between the impurity and the fermions, the low temperature behavior of the system is governed by the two-channel Kondo effect, leading to the impurity becoming completely opaque to the spin excitations of the gas. As well as the known spectral signatures of the two-channel Kondo effect, we find that the low temperature mobility of the resulting `Kondo polaron' takes the universal form $μ\to \frac{3\hbar v_F^2}{2πk_B^2T^2}$, in sharp contrast to the spinless case where $μ\propto T^{-4}$.

Antero de Quental, the Coimbrã years - 1858-1865
Creators: name: Eldridge, Claire A. Z.
Publisher: name: University of British Columbia
Year: 2010

description: The theme of the essay is the evolution of Antero de Quental from the childhood years in the sleepy island of São Miguel, Azores, up to the famous controversy called the Questão Coimbrã in which Antero played a major part. The first chapter depicts the circumstances of Antero's childhood: the liberalism of his "morgado" grandfather, father and brother, the strong religious feelings of his mother, the high status of the families on both sides. It discusses the impact of A. F. de Castilho and his Sociedade dos Amigos das Letras e Artes on Antero's island world, and the influence of Alexandre Herculano's mystic ode, "Deus". It covers the early schooling years up to the departure for serious education on the continent. The second chapter deals with Antero's arrival in Coimbra, his disappointment and frustration at the complacency of his professors, and the revolutionary impact of his reading of Henriques de Nogueira, Lamartine, Michelet, Proudhon, etc… It introduces Antero's friends. It follows the development of the poet up to the publication of the "Sonetos" (1861), under the influence of João de Deus: religious, mystic, intimate poetry inspired by their mutual admiration of Camões. In chapter III, we examine the evolution of Antero's social conscience. In his definition of art, he accepted the concept of art as corresponding to beauty but, convinced that poetry is also an expression of man's moral conscience and an agent for social reform, he wrote a collection of militant verse, his "Odes Modernas" (mostly 1862-1863), published for the first time in 1865.

description: The IR emission of dust heated by stars provides critical information for galaxy evolution studies. Unfortunately, observations are often limited to the MIR, making templates a necessity. Previously published templates were based on small samples of luminous galaxies, not necessarily representative of normal star-forming galaxies. We construct new dust templates, including instrument-specific relations and software tools that facilitate the estimation of the TIR luminosity and SFR based on one or several fluxes up to z=4. For the first time the templates include a dependence on both TIR luminosity and the sSFR, thereby increasing their reliability and utility. We also provide formulae for calculating TIR luminosities and SFR from JWST F2100W observations at 0
description: Accepted for publication in A&A, 25 pages, 17 figures. See Fig. 3, 9, and 10 for the templates. The estimators and the templates are available at https://salims.pages.iu.edu/bosa/. The software tools can be downloaded from https://github.com/mboquien/bosa/

description: We present results on baryon number, strangeness and electric charge fluctuations in QCD at non-zero density and temperature obtained from lattice calculations with almost physical quark masses. At vanishing chemical potential, i.e. under conditions almost realized at RHIC and the LHC, quartic fluctuations of net baryon number and strangeness are large in a narrow temperature interval characterizing the transition region from the low to the high temperature phase. Our results are based on Taylor expansions in light and strange quark chemical potentials, i.e. we rigorously compute corrections to bulk thermodynamic quantities at non vanishing chemical potential, by performing a Taylor expansion in $μ/T$. We find non-monotonic behavior for the radius of convergence of this series, which could be a hint for a critical end-point in the ($T,μ$)-plane.

description: Explicitly modeling emotions in dialogue generation has important applications, such as building empathetic personal companions. In this study, we consider the task of expressing a specific emotion for dialogue generation. Previous approaches take the emotion as an input signal, which may be ignored during inference. We instead propose a search-based emotional dialogue system by simulated annealing (SA). Specifically, we first define a scoring function that combines contextual coherence and emotional correctness. Then, SA iteratively edits a general response and searches for a sentence with a higher score, enforcing the presence of the desired emotion. We evaluate our system on the NLPCC2017 dataset. Our proposed method shows 12% improvements in emotion accuracy compared with the previous state-of-the-art method, without hurting the generation quality (measured by BLEU).

description: Integrated photonic spectrographs offer an avenue to extreme miniaturization of astronomical instruments, which would greatly benefit extremely large telescopes and future space missions. These devices first require optimization for astronomical applications, which includes design, fabrication and field-testing. Given the high costs of photonic fabrication, Multi-Project Wafer (MPW) SiN offerings, where a user purchases a portion of a wafer, provide a convenient and affordable avenue to develop this technology. In this work we study the potential of two commonly used SiN waveguide geometries by MPW foundries, i.e. square and rectangular profiles to determine how they affect the performance of mid-high resolution arrayed waveguide grating spectrometers around 1.5 $μ$m. Specifically, we present results from detailed simulations on the mode sizes, shapes, and polarization properties, and on the impact of phase errors on the throughput and cross talk as well as some laboratory results of coupling and propagation losses. From the MPW-run tolerances and our phase-error study, we estimate that an AWG with R $\sim$ 10,000 can be developed with the MPW runs and even greater resolving power is achievable with more reliable, dedicated fabrication runs. Depending on the fabrication and design optimizations, it is possible to achieve throughputs $\sim 60\%$ using the SiN platform. Thus, we show that SiN MPW offerings are highly promising and will play a key role in integrated photonic spectrograph developments for astronomy.

Statistics, Social Science, and the Culture of Objectivity
Creators: name: Porter, Theodore M.
Publisher: name: Austrian Journal of Historical Studies
Year: 1996

description: Contrary to the presumption common in the social sciences, that culture and rationality are in opposition and mutually exclusive of each other - a presumption shared by such different approaches as game theory, rational choice theory and cultural anthropology - , the author emphazises that cultures always have their own rationalities. Standards of reasonableness cannot be thought of as universal, but inevitably reflect culture. Rationality is conditioned, so the author argues, by political forms, economic circumstances, institutions, laws, and customs. This is also true for cultures of objectivity, which are based on the rejection of what is usually conceived of as subjective, linked to emotions and to the personal. The examples of the historic struggles relating to the profession of accountants and the invention of cost-benefit analysis in the United States enable the author to put forward the argument that the quest for objectivity is in itself the cultural expression of a need emerging within societies where political order is not self- evident. Not only bureaucracies impose general standards of administration to avoid severe political conflicts, but various outsiders in different spheres of a society try and manage to gain credibility by escaping what is tainted by personal interest and subjectivity. From this perspective, the author identifies the insistence on impersonal rules in science as a cultural response to conditions of distrust within the corresponding disciplines and in the larger society, and discusses the uses made of statistics in the social sciences characterised by the reduction of quantification to impersonal, unitary, almost mechanical, strategies of analysis.

description: Extragalactic sources from the IRAS Faint Source Catalog (FSC) which have the optically faintest magnitudes (E > 18) were selected by spatial coincidence with a source in the FIRST radio survey, and 28 of these sources have been observed with the Infrared Spectrograph on Spitzer (IRS). While an infrared source is always detected with the IRS at the FIRST position, only ~ 50% of the infrared sources are real FSC detections, as estimated from the number of sources for which the fv(25um) determined with the IRS is fainter than the sensitivity limit for the FSC. Sources have 0.12 < z < 1.0 and luminosities (ergs per s) 43.3 < log[vLv(5.5um)] < 46.7, encompassing the range from local ULIRGs to the most luminous sources discovered by Spitzer at z ~ 2. Detectable PAH features are found in 15 of the sources (54%), and measurable silicate absorption is found in 19 sources (68%); both PAH emission and silicate absorption are present in 11 sources. PAH luminosities are used to determine the starburst fraction of bolometric luminosity, and model predictions for a dusty torus are used to determine the AGN fraction of luminosity in all sources based on log[vLv(5.5um)]. Approximately half of the sources have luminosity dominated by an AGN and approximately half by a starburst. The ratio of infrared to radio flux, defined as q = log[fv(25um)/fv(1.4 GHz)], does not distinguish between AGN and starburst for these sources.

description: The light curve of an exoplanetary transit can be used to estimate the planetary radius and other parameters of interest. Because accurate parameter estimation is a non-analytic and computationally intensive problem, it is often useful to have analytic approximations for the parameters as well as their uncertainties and covariances. Here we give such formulas, for the case of an exoplanet transiting a star with a uniform brightness distribution. We also assess the advantages of some relatively uncorrelated parameter sets for fitting actual data. When limb darkening is significant, our parameter sets are still useful, although our analytic formulas underpredict the covariances and uncertainties.

description: Lawler, Schramm and Werner showed that the scaling limit of the loop-erased random walk on $\mathbb{Z}^2$ is $\mathrm{SLE}_2$. We consider scaling limits of the loop-erasure of random walks on other planar graphs (graphs embedded into $\mathbb{C}$ so that edges do not cross one another). We show that if the scaling limit of the random walk is planar Brownian motion, then the scaling limit of its loop-erasure is $\mathrm{SLE}_2$. Our main contribution is showing that for such graphs, the discrete Poisson kernel can be approximated by the continuous one. One example is the infinite component of super-critical percolation on $\mathbb{Z}^2$. Berger and Biskup showed that the scaling limit of the random walk on this graph is planar Brownian motion. Our results imply that the scaling limit of the loop-erased random walk on the super-critical percolation cluster is $\mathrm{SLE}_2$.

The development of a microcomputer-based perioperative patient monitoring system
Creators: name: Cox, Neil B.
Publisher: name: University of British Columbia

description: A computer-based perioperative patient monitoring system, called the Mobile Operation Monitoring for Anesthetists or MOMA, is discussed. The primary objective of this work was to produce a flexible, mobile prototyping system which could be used to develop a clinically useful tool to aid the anesthetist in the task of patient maintenance during anesthesia. Potential application areas are discussed along with the limitations and necessary design considerations. The system developed for this thesis uses a PDP-11V03-L microcomputer system with an A/D converter and dual double-density floppy disk drive to acquire, process, and store four channels of EEG along with up to four channels of non-EEG data. The data is displayed on a Tektronix 4025 video graphics terminal in a number of user-selectable display formats. A currently popular EEG display format (Density modulation of the compressed Spectral Array or (DSA)) is modified to simplify the determination of long-term EEG trends. This display format is presented along with non-EEG data in order to facilitate comparisons between parameters. The user can recall any EEG display which appeared earlier in the operation without interfering with data acquisition, processing, and storage. The keyboard is configured in an easy-to-use format with the keys clearly labelled and grouped according to their function. Each command is generated by typing a single key. A facility for the entry of comments through the keyboard was implemented so that the time of occurrence of certain significant events during surgery, such as pharmacological intervention, can be tagged. These tags are then displayed along with the automatically acquired data. An emphasis was placed on maximizing MOMA's flexibility and an attempt was made to anticipate and simplify the modifications which may be desirable in the future. Programs are written in Fortran, are fully documented, and are run under the RT-11 operating system. The potential usefulness of the system and the non-technical documentation was assessed by five anesthetists practicing at Vancouver General Hospital (VGH). It was their opinion that MOMA is a potentially useful addition to the operating room and each assessor expressed an interest in being involved in future clinical applications. The adequacy and overall quality of the programs and related technical documentation was assessed by an engineer employed in the EEG department at VGH and experienced in both Fortran and RT-11. It was his opinion that the programs and related documentation are adequate and will be useful for the development of a clinically useful patient monitoring system.

description: We perform a canonical change of the field variables of light-cone gauge massless QCD to obtain a lagrangian whose terms are proportional up to polarisation factors to MHV amplitudes and continued off shell by the CSW prescription. We solve for this transformation as a series expansion to all orders in the new fields, and use this to prove that the resulting vertices are indeed MHV vertices as claimed. We also demonstrate how this works explicitly for the vertices with: two quarks and two gluons, four quarks, and a particular helicity configuration of two quarks and three gluons. Finally, we generalise the construction to massive QCD.
description: **Important New Material:** Proof that vertices are MHV amps off-shell, **Plus** results for all MHV verts with massive quarks. Clarifications made, esp. on the link between massless quark-gluon vertices and known results, and the choice of massive poln. spinors. Citations revised. 42 pages, 2 figures, 4 tables.

description: In this note we prove the analogue of the Atiyah-Segal completion theorem for equivariant twisted K-theory in the setting of an arbitrary compact Lie group G and an arbitrary twisting of the usually considered type. The theorem generalizes a result by C. Dwyer, who has proven the theorem for finite G and twistings of a more restricted type. While versions of the general result have been known to experts, to our knowledge no proof appears in the current literature. Our goal is to fill in this gap. The proof we give proceeds in two stages. We first prove the theorem in the case of a twisting arising from a graded central extension of G, following the Adams-Haeberly-Jackowski-May proof of the classical Atiyah-Segal completion theorem. After establishing that the theorem holds for this special class of twistings, we then deduce the general theorem by a Mayer-Vietoris argument.

description: Absorption-selected galaxies offer an effective way to study low-mass galaxies at high redshift. However, the physical properties of the underlying galaxy population remains uncertain. In particular, the multiphase circum-galactic medium is thought to hold key information on gas flows into and out of galaxies that are vital for galaxy evolution models. Here we present ALMA observations of CO molecular gas in host galaxies of H_2-bearing absorbers. In our sample of six absorbers we detect molecular gas-rich galaxies in five absorber fields although we did not target high-metallicity (>50 per cent solar) systems for which previous studies reported the highest detection rate. Surprisingly, we find that the majority of the absorbers are associated with multiple galaxies rather than single haloes. Together with the large impact parameters these results suggest that the H_2-bearing gas seen in absorption is not part of an extended disk, but resides in dense gas pockets in the circum-galactic and intra-group medium.

description: A MEMS based tribometer has been developed that can be read out with nanometer and nano-Newton resolution, approaching the resolution and sensitivity of a friction force microscope (FFM). It can be used to study friction of MEMS device sidewall surfaces. We find repeatable but irregular stick-slip behavior related to the surface roughness or surface modification (wear), depending on the normal force between the sliding surfaces. In addition, we show that normal force modulation can decrease the apparent friction even though the average normal force remains the same. This may be a technologically viable way to reduce friction and wear in microscopic contacts.

description: This article is an updated version of the article that was published in the Electronic Journal of Differential Equations on 10. July 2010. Two footnotes have been added. One corrects a minor error not influencing the proof, the second is only a clarifying text to the existing proof. A discussion how the published article solves the Clay Millennium Prize problem on the Navier-Stokes equations is added, the critizism against the published article is answered and a discussion how the Clay problem statement should be corrected is included. The article gives explicit solutions to the space-periodic Navier-Stokes problem with non-periodic pressure. These type of solutions are not unique and by using such solutions one can construct a periodic, smooth, divergence-free initial vector field allowing a space-periodic and time-bounded external force such that there exists a smooth solution to the 3-dimensional Navier-Stokes equations for incompressible fluid with those initial conditions, but the solution cannot be continued to the whole space.
