L’harmonie, me disait-il, n’est qu’un accessoire éloigné dans la musique imitative; il n’y a dans l’harmonie proprement dite aucun principe d’imitation. Elle assure, il est vrai, les intonations; elle porte témoignage de leur justesse; et, rendant les modulations plus sensibles, elle ajoute de l’énergie à l’expresson, et de la grâce au chant. Mais c’est de la seule mélodie que sort cette puissance invincible des accents passionés; c’est d’elle que dérive tout le pouvoir de la musique sur l’âme. Formez les plus savantes successions d’accords sans mélange de mélodie, vous serez ennuyés au bout d’un quart d’heure. De beaux chants sans aucune harmonie sont longtemps à l’épreuve de l’ennui. Que l’accent du sentiment anime les chants les plus simples, ils seront intéressants. Au contraire, une mélodie qui ne parle point chante toujours mal, et la seule harmonie n’a jamais rien su dire au coeur.

When people look under the hood, we want them to be impressed with the neatness, consistency, and attention to detail that they perceive. We want them to be struck by the orderliness. We want their eyebrows to rise as they scroll through the modules. We want them to perceive that professionals have been at work. If instead they see a scrambled mass of code that looks like it was written by a bevy of drunken sailors, then they are likely to conclude that the same inattention to detail pervades every other aspect of the project.

The clearest short-term yardstick may be the PSA nadir (discussed above). One study of 743 patients at Memorial Sloan-Kettering Cancer Center in New York confirmed that higher-intensity radiation does a better job of achieving a rock-bottom PSA level. Of the men who received higher doses—76 to 81 Gy—90 percent achieved a PSA nadir of 1.0 ng/ml or less; 76 percent of men who received 70 Gy and 56 percent of men who received 64.8 Gy achieved those low PSA levels. But there was a trade-off—the men who received higher doses of radiation also had a significantly higher rate of gastrointestinal side effects, urinary tract complications, and impotence. To overcome these side effects at high doses, intensity-modulated radiation therapy

Mi-a venit foarte greu sa ma afirm alaturi de gandurile mele. Era un demon in mine, iar in cele din urma prezenta lui a fost decisiva. Ma domina si mi-o lua inainte, iar cand se intampla sa nu mai tin seama de nimic, era fiindca el ma presa. Nu ma puteam opri niciodata la ceea ce obtinusem deja. Trebuia sa continui sa alerg, pentru a-mi ajunge din urma viziunea. Intrucat, dupa cum e lesne de inteles, contemporanii mei nu puteau percepe viziunea mea, vedeau in mine doar pe cineva care fuge aiurea.
Am ofensat multi oameni; caci, indata ce observam ca nu ma intelegeau, pentru mine cazul era incheiat. Trebuia sa merg mai departe. Exceptie facand pacientii mei, n-aveam rabdare cu oamenii. Intotdeauna trebuia sa-mi urmez legea interioara care-mi era impusa si nu-mi lasa libertatea alegerii. Ce-i drept insa, n-o urmam de fiecare data. Cum am putea s-o scoatem la capat fara inconsecvente?
Pentru unii oameni eram nemijlocit prezent, in masura in care se aflau in contact cu lumea launtrica; dar apoi se putea intampla ca, brusc, sa nu mai fiu acolo cu ei, dat fiind ca nu mai exista nimic care sa ma lege de ei. Am invatat anevoie ca oamenii continua sa fie prezenti, chiar si atunci cand nu mai au nimic a-mi spune. Multi trezeau in mine sentimentul unei umanitati vii, dar numai cand apareau in cercul magic al psihologiei, devenind vizibili; in clipa urmatoare, cand farul isi indrepta raza in alta directie, nu mai exista nimic. Unii oameni ma puteau interesa in modul cel mai intens, pentru ca, de indata ce ii "descifram", farmecul sa dispara. Mi-am facut multi dusmani astfel. Dar, ca om creator, esti la discretia demonului, nu esti liber, ci inlantuit si manat de el. "... o putere rusinos ne smulge / Inima. / Caci jertfa cere orice e ceresc. / Dar cand un zeu este lasat deoparte, / N-aduce nici un bine." (Holderlin, Imnuri si ode)
Lipsa de libertate m-a umplut de tristete. Adesea aveam senzatia ca ma gasesc pe un camp de lupta. Acum ai cazut tu, bunul meu camarad, dar eu trebuie sa continui! Eu nu pot, nu, nu pot ramane! Caci "o putere rusinoasa ne smulge inima". Mi-esti drag, te iubesc chiar, dar nu pot ramane! Pe moment, este ceva sfasietor. Caci eu insumi sunt victima, nu pot, sa raman. Dar demonul aranjeaza lucrurile astfel incat s-o scoatem la capat, iar binecuvantata inconsecventa are grija ca, in contrast flagrant cu "infidelitatea" mea, sa pot ramane credincios intr-o masura nebanuita.

As an anology, consider the word structure. In bacteria, the gene is embedded in the genome in precisely that format, structure, with no breaks, stuffers, interpositions, or interruptions. In the human genome, in contrast, the word is interrupted by intermediate stretches of DNA: s...tru...ct...ur...e.
The long stretches of DNA marked by the ellipses (...) do not contain any protein-encoding information. When such an interrupted gene is used to generate a message-i.e., when DNA is used to build RNA-the stuffer frragments are excised from the RNA message, and the RNA is stitched together again with the intervening pieces removed: s...tru...ct...ur...e became simplified to structure. Roberts and Sharp later coined a phrase for the process: gene splicing or RNA splicing (since the RNA message of the gene was "spliced" to removed the stuffer fragments).
At first, this split structure of genes seemed puzzling: Why would an animal genome waste such long stretches of DNA splitting genes into bits and pieces, only to stitch them back into a continuous message? But the inner logic of split genes soon became evident: by splitting genes into modules, a cell could generate bewildering combinations of messages out of a single gene. The word s...tru...c...t...ur...e can be spliced to yield cure and true and so forth, thereby creating vast numbers of variant messages-called isoforms-out of a single gene. From g...e...n...om...e you can use splicing to generate gene, gnome, and om. And modular genes also had an evolutionary advantage: the individual modules from different genes could be mixed and matched to build entirely new kinds of genes (c...om...e...t). Wally Gilbert, the Harvard geneticist, created a new word for these modules; he called them exons. The inbetween stuffer fragments were termed introns.

Social success in primitive society, therefore, is achieved by those who are perceived to help the group, not by those who cheat and sponge from it, and cheating as a successful strategy can only work when a number of basic social changes have taken place. These are: much larger societies with a high percentage of people who are strangers; the growth of trade and commerce, particularly through the medium of money; the accumulation of material wealth; and the growth of complex bureaucratic systems of redistribution. So it should be obvious that it is not the hunter-gatherer band but modern industrial society that provides by far the most advantageous environment for freeloaders to flourish, such as bogus welfare claimants, tax evaders, and confidence-tricksters of every kind, but evolution has sadly neglected to provide us with any “cheater-detection” module to cope with this.

The 1byone Aluminum combination open air laser Christmas projector is an exceptional contrasting option to the standard model recorded at number 1 above.
Being produced using aluminum, as opposed to hard plastic, the unit carries a marginally higher sticker price, yet the additional cash gets you a projector that will last you for quite a while and will withstand even the most extraordinary of open air temperatures and conditions.
You can set the unit up to turn on and off as per your inclinations, utilizing the straightforward remote control to change settings.
Show Options
The essential show offered by the 1byone Aluminum projector is that of thousands of green and red stars. There is a sum of 9 distinct settings. Glimmering, squinting, and strong light shows, and in addition a decision of red, green, or both red and green lights, empower you to pick the show that you like best, or that best fits the season.
Despite the fact that the lights are charged as a Christmas show and are regularly used to enlighten the outside of a property, they can be utilized for any festival, and they can be utilized inside or outside.
Components
The projector is controlled by mains power. The remote control, which ought to be utilized with a reasonable observable pathway of the focal module, works at up to 30ft away, and it will work a temperature as low as - 35°C.
The power link is an advantageous 11.5ft long, and 25ft from the surface you need covering; you can accomplish a scope of 2,100 square feet.
It is not just reasonable for use on the outside of homes, yet can light workplaces and shops, and it can even be utilized inside to light the inside of a property and to make a happy feeling.

On sait ce qui fait tenir physiquement le béton : l'hydratation du ciment transforme ses phases silicatées en silicate de calcium hydraté, dont la structure assure la cohésion des granulats et la résistance du matériau. Mais qu'est-ce qui le fait tenir ontologiquement ?
Dit autrement, c'est quoi le monde du béton ?
Le ciment standardisé le plus commun, dit "Portland", a été mis au point au début du XIXe siècle. Il accompagne l'essor du capitalisme industriel. Hyper modulable, peu onéreux, facile de mise en oeuvre comme à détruire, les qualités du béton de ciment donnent depuis lors aux politiques et aménageurs une grande liberté pour configurer et reconfigurer l'espace. Et cette reconfiguration n'a pas cessé depuis que les humains s'agglomèrent dans les villes, suivant en substance les mouvements de concentration du capital.
Le béton matérialise ce rapport dans des infrastructures dédiées à l'accélération des flux de marchandises, qu'il s'agisse d'information, d'énergie, de biens manufacturés, ou de travailleurs. Frets, entrepôts de stockage, hubs de tri, transporteurs, data centers, fibre optique, plateformes "virtuelles" : les grands réseaux logistiques et informationnels synchronisent les métropoles entre elles sur la cadence du marché. Zébrant les territoires, cette couche dessine une pieuvre logistique faite de routes, ponts, tunnels connectant entrepôts, ports et aéroports. N'ayant que faire des particularités des territoires traversés, au mépris de celles et ceux qui y habitent, la logistique trace tout droit à travers bourgs, champs, zones naturelles et montagnes. Les campagnes sont reléguées aux fonctions de voies de transit d'un côté, et en ressources alimentaires et énergétiques de l'autre.

SUMMARY A vast array of additional statistical methods exists. In this concluding chapter, we summarized some of these methods (path analysis, survival analysis, and factor analysis) and briefly mentioned other related techniques. This chapter can help managers and analysts become familiar with these additional techniques and increase their access to research literature in which these techniques are used. Managers and analysts who would like more information about these techniques will likely consult other texts or on-line sources. In many instances, managers will need only simple approaches to calculate the means of their variables, produce a few good graphs that tell the story, make simple forecasts, and test for significant differences among a few groups. Why, then, bother with these more advanced techniques? They are part of the analytical world in which managers operate. Through research and consulting, managers cannot help but come in contact with them. It is hoped that this chapter whets the appetite and provides a useful reference for managers and students alike. KEY TERMS Endogenous variables Exogenous variables Factor analysis Indirect effects Loading Path analysis Recursive models Survival analysis Notes 1. Two types of feedback loops are illustrated as follows: 2. When feedback loops are present, error terms for the different models will be correlated with exogenous variables, violating an error term assumption for such models. Then, alternative estimation methodologies are necessary, such as two-stage least squares and others discussed later in this chapter. 3. Some models may show double-headed arrows among error terms. These show the correlation between error terms, which is of no importance in estimating the beta coefficients. 4. In SPSS, survival analysis is available through the add-on module in SPSS Advanced Models. 5. The functions used to estimate probabilities are rather complex. They are so-called Weibull distributions, which are defined as h(t) = αλ(λt)a–1, where a and 1 are chosen to best fit the data. 6. Hence, the SSL is greater than the squared loadings reported. For example, because the loadings of variables in groups B and C are not shown for factor 1, the SSL of shown loadings is 3.27 rather than the reported 4.084. If one assumes the other loadings are each .25, then the SSL of the not reported loadings is [12*.252 =] .75, bringing the SSL of factor 1 to [3.27 + .75 =] 4.02, which is very close to the 4.084 value reported in the table. 7. Readers who are interested in multinomial logistic regression can consult on-line sources or the SPSS manual, Regression Models 10.0 or higher. The statistics of discriminant analysis are very dissimilar from those of logistic regression, and readers are advised to consult a separate text on that topic. Discriminant analysis is not often used in public

Perhaps you were just tired of working on this program and wanted it to be over. Or maybe you looked at the backlog of other stuff that you had promised to get done and realized that you needed to slam this module together so you could move on to the next. We’ve all done it. We’ve all looked at the mess we’ve just made and then have chosen to leave it for another day.

Professional developers are so certain of their code and tests that they are maddeningly casual about making random, opportunistic changes. They'll change the name of a class, on a whim. They'll notice a long-ish method while reading through a module and repartition it as a matter of course They'll transform a switch statement into polymorphic deployment, or collapse an inheritance hierarchy into a chain-of-command. In short, they treat software the way a sculptor treats clay-they continuously shape and mold it.

subiect, ceea ce de fapt conduce la suprimarea principiului noncon tradicţiei. " La modul general - spune Aristotel --'- cei care contestă pr inc ipiul noncontradicţiei suprimă Fiinţa. Căci este necesar ca ei să pretindă că toate cele sunt contexte, sau relaţii contextuale, şi că nu există ceva ce omul s au anima lul sunt intrinsec." Trebuie s ă spunem totuşi că legătura dintre relativismul epistemologie ş i negarea principiului noncontradicţiei nu este chi a r atât d e necesară log i c pe cât i s e părea l u i Aristotel : ma i înt â i afirmaţia lui Protagoras poa t e fi înţeleasă nu numai i n d i vidua l - subi ectiv ( o r i c e o m e măsura tuturor lucrurilor), ci ş i specific-kantian ( omu l în general dă măsura lucrurilor).

Totuşi este de netăgăduit că, filozofic vorbind, există o legă tură între relativismul ontologic ş i cel epistemologie, pe de -o parte, şi sofistică, pe de a l t ă parte, şi că Aristotel nu greşea foarte mult asociindu-le. Aşadar, să admitem că, dacă se suprimă Fiinţa, în final, s e suprimă principiul noncontradicţiei.

General recommendations are safe for all types of chemotherapy. • Multiple vitamin: — Vitamin A: 5000 IU — Mixed natural carotenoids: 10,000-25,000 IU — B complex: 25-50 mg — Folic acid: 400-800 μg — Vitamin B12: 200-1000 μg — Vitamin E succinate: 400 IU — Vitamin C: 500-1000 mg — Vitamin D 400-800 IU — Trace minerals: full complement • Melatonin: 20 mg at bedtime • Vitamin C: 3000-10,000 mg q.d. in divided doses according to bowel tolerance • Fish oils: to provide 2 g total combined eicosapentaenoic acid and docosahexaenoic acid daily • Mushroom extracts/immune support: use a variety of immune modulators, switching them regularly to avoid downregulation of receptors. Standard doses for Coreolis versicolor mushroom is 3 g of the extract daily. Suggested dosage for maitake D fraction is 0.5-1.0 mg of extract per kilogram body weight. Other botanical immune modulators may be used as desired. • Enzymes: use pancreatic enzymes with meals and mixed enteric-coated enzymes between meals. • Green tea: capsules and beverages to total the equivalent of 5-10 cups daily. Caffeinated form is preferred if patient tolerates caffeine. • Whey protein shake: administer with fruit daily as a source of easily assimilated protein and amino acids, particularly glutamine.

One downfall of numpy’s optimization of vector operations is that it only occurs on one operation at a time. That is to say, when we are doing the operation A * B + C with numpy vectors, first the entire A * B operation completes, and the data is stored in a temporary vector; then this new vector is added with C. The in-place version of the diffusion code in Example 6-14 shows this quite explicitly. However, there are many modules that can help with this. numexpr is a module that can take an entire vector expression and compile it into very efficient code that is optimized to minimize cache misses and temporary space used. In addition, the expressions can utilize multiple CPU cores (see Chapter 9 for more information) and specialized instructions for Intel chips to maximize the speedup. It is very easy to change code to use numexpr: all that’s required is to rewrite the expressions as strings with references to local variables. The expressions are compiled behind the scenes (and cached so that calls to the same expression don’t incur the same cost of compilation) and run using optimized code. Example 6-19 shows the simplicity of changing the evolve function to use numexpr. In this case, we chose to use the out parameter of the evaluate function so that numexpr doesn’t allocate a new vector to which to return the result of the calculation.

The only way to prove that your software is easy to change is to make easy changes to it. And when you find that the changes aren’t as easy as you thought, you refine the design so that the next change is easier. When do you make these easy changes? All the time! Every time you look at a module you make small, lightweight changes to it to improve its structure.

When Apollo 9 lunar module pilot Russell “Rusty” Schweickart saw Earth from space, he said, “From the moon, the Earth is so small and so fragile and such a precious little spot in that universe that you can block it out with your thumb. Then you realize that on that spot, that little blue and white thing, is everything that means anything to you—all of history and music and poetry and art and death and birth and love, tears, joy, games, all of it right there on that little spot that you can cover with your thumb. And you realize from that perspective that you’ve changed forever, that there is something new there, that the relationship is no longer what it was.

In general, it is harmful to depend on modules that contain more than you need. This is obviously true for source code dependencies that can force unnecessary recompilation and redeployment—but it is also true at a much higher, architectural level.

To the software architect, however, the answer is clear: OO is the ability, through the use of polymorphism, to gain absolute control over every source code dependency in the system. It allows the architect to create a plugin architecture, in which modules that contain high-level policies are independent of modules that contain low-level details. The low-level details are relegated to plugin modules that can be deployed and developed independently from the modules that contain high-level policies.

What do we talk about when we talk about architecture? As with any metaphor, describing software through the lens of architecture can hide as much as it can reveal. It can both promise more than it can deliver and deliver more than it promises. The obvious appeal of architecture is structure, and structure is something that dominates the paradigms and discussions of software development—components, classes, functions, modules, layers, and services, micro or macro. But the gross structure of so many software systems often defies either belief or understanding—Enterprise Soviet schemes destined for legacy, improbable Jenga towers reaching toward the cloud, archaeological layers buried in a big-ball-of-mud slide. It’s not obvious that software structure obeys our intuition the way building structure does.

Be prepared to work hard while reading this book. This is not a “feel good” book that you can read on an airplane and finish before you land. This book will make you work, and work hard. What kind of work will you be doing? You’ll be reading code—lots of code. And you will be challenged to think about what’s right about that code and what’s wrong with it. You’ll be asked to follow along as we take modules apart and put them back together again. This will take time and effort; but we think it will be worth it.

It is the perversity of software that a module that you have designed to be easy to change can be made difficult to change by someone else simply hanging a dependency upon it.

Katia, Shelby, Tim, Shiro and I are doing our best to play cards in the lounge. Shelby got some adhesive so we can stick them to the coffee table, but it’s still a challenge and some of them escape to float away. We’d be in the Centrifuge Module, but we don’t want to end up, you know, dead. Shiro says, “So, now that we’re on our way, I think it’s time we start getting real. We need to be prepared for what’s out there.” “I think we’re about as prepared as we can get,” Shelby comments, discarding. “In all the training, we never had any discussions about motives.” “Motives?” Tim asks. “Yes,” Shiro says. “For example, look at the crew the aliens chose. With the exception of Jim, all of us are young.” “Well that’s self-explanatory, isn’t it?” says Tim. “Why send older, less physically fit individuals on such a physically rigorous journey? No offense, Jim.” “The females are younger than the males, but all of us are of reproductive age.” He looks up from his cards, “Doesn’t that make you a little curious what they have in mind?” “Shiro! You’re making me uncomfortable,” Shelby says. Looking at Katia, Shiro says, “And you’re the youngest, Katia. Very young, in fact, and intelligent on a scale beyond the reach of the vast majority of humans.” He glances from side to side, “All of us, in fact, are exceptional. With the exception of you, Jim. No offense, of course.” “None taken,” I say. “Full house.” Everyone groans and I collect all the chips we have placed in a Ziploc bag. Tim asks, “Are you suggesting that they intend to keep us as pets and breed us, or something? Because that’s impossible. You know all the men on the crew have been sterilized.” “Yes, I know. But do you think that, if they have the technology to do what they have already done, they might also be able to overcome such a hurdle? They will have our DNA, and three perfectly viable wombs to work with. That should be enough.” Shelby exclaims, “That is enough! Good grief, Shiro. Are you trying to give us nightmares?” “I just want us all to be prepared for all eventualities.” Blinking, her brows furrowed, Shelby says, “How considerate of you. That’s enough preparation for today.” ∆v∆v∆v∆v∆

Sun power’s image as the province of baling-wire hippies was at odds with reality. Today’s multibillion-dollar photovoltaic industry owes its existence mainly to the Pentagon and Big Oil. The first wide-scale use of solar panels had come in the 1960s: powering military satellites, which couldn’t use fossil fuels (too bulky to lift into space) or batteries (impossible to recharge in orbit). By the 1970s photovoltaics were cheaper, but the industry had acquired only one major new user: the petroleum industry. Some 70 percent of the solar modules sold in the United States were bought to run offshore drilling platforms.
