Wiki Wiki Summary
Arithmetic Arithmetic (from Ancient Greek ἀριθμός (arithmós) 'number', and τική [τέχνη] (tikḗ [tékhnē]) 'art, craft') is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots. In the 19th century, Italian mathematician Giuseppe Peano formalized arithmetic with his Peano axioms, which are highly important to the field of mathematical logic today.
Operation Mincemeat Operation Mincemeat was a successful British deception operation of the Second World War to disguise the 1943 Allied invasion of Sicily. Two members of British intelligence obtained the body of Glyndwr Michael, a tramp who died from eating rat poison, dressed him as an officer of the Royal Marines and placed personal items on him identifying him as the fictitious Captain (Acting Major) William Martin.
Special Activities Center The Special Activities Center (SAC) is a division of the Central Intelligence Agency responsible for covert operations and paramilitary operations. The unit was named Special Activities Division (SAD) prior to 2015.
Operations management Operations management is an area of management concerned with designing and controlling the process of production and redesigning business operations in the production of goods or services. It involves the responsibility of ensuring that business operations are efficient in terms of using as few resources as needed and effective in meeting customer requirements.
Surgery Surgery is a medical or dental specialty that uses operative manual and instrumental techniques on a person to investigate or treat a pathological condition such as a disease or injury, to help improve bodily function, appearance, or to repair unwanted ruptured areas.\nThe act of performing surgery may be called a surgical procedure, operation, or simply "surgery".
Bitwise operation In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits. It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.
Operation (mathematics) In mathematics, an operation is a function which takes zero or more input values (called operands) to a well-defined output value. The number of operands (also known as arguments) is the arity of the operation.
Yoda conditions In programming jargon, Yoda conditions (also called Yoda notation) is a programming style where the two parts of an expression are reversed from the typical order in a conditional statement. A Yoda condition places the constant portion of the expression on the left side of the conditional statement.
Twenty-one Conditions The Twenty-one Conditions, officially the Conditions of Admission to the Communist International, refer to the conditions, most of which were suggested by Vladimir Lenin, to the adhesion of the socialist parties to the Third International (Comintern) created in 1919. The conditions were formally adopted by the Second Congress of the Comintern in 1920.
Standard temperature and pressure Standard temperature and pressure (STP) are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data. The most used standards are those of the International Union of Pure and Applied Chemistry (IUPAC) and the National Institute of Standards and Technology (NIST), although these are not universally accepted standards.
Wolfe conditions In the unconstrained minimization problem, the Wolfe conditions are a set of inequalities for performing inexact line search, especially in quasi-Newton methods, first published by Philip Wolfe in 1969.In these methods the idea is to find\n\n \n \n \n \n min\n \n x\n \n \n f\n (\n \n x\n \n )\n \n \n {\displaystyle \min _{x}f(\mathbf {x} )}\n for some smooth \n \n \n \n f\n :\n \n \n R\n \n \n n\n \n \n →\n \n R\n \n \n \n {\displaystyle f\colon \mathbb {R} ^{n}\to \mathbb {R} }\n . Each step often involves approximately solving the subproblem\n\n \n \n \n \n min\n \n α\n \n \n f\n (\n \n \n x\n \n \n k\n \n \n +\n α\n \n \n p\n \n \n k\n \n \n )\n \n \n {\displaystyle \min _{\alpha }f(\mathbf {x} _{k}+\alpha \mathbf {p} _{k})}\n where \n \n \n \n \n \n x\n \n \n k\n \n \n \n \n {\displaystyle \mathbf {x} _{k}}\n is the current best guess, \n \n \n \n \n \n p\n \n \n k\n \n \n ∈\n \n \n R\n \n \n n\n \n \n \n \n {\displaystyle \mathbf {p} _{k}\in \mathbb {R} ^{n}}\n is a search direction, and \n \n \n \n α\n ∈\n \n R\n \n \n \n {\displaystyle \alpha \in \mathbb {R} }\n is the step length.
Conditions (album) Conditions is the debut studio album by Australian rock band The Temper Trap, released in Australia through Liberation Music on 19 June 2009. It was later released in the United Kingdom on 10 August 2009.
Conditions races Conditions races are horse races in which the weights carried by the runners are laid down by the conditions attached to the race. Weights are allocated according to the sex of the runners, with female runners carrying less weight than males; the age of the runners, with younger horses receiving weight from older runners to allow for relative maturity, referred to as weight for age; and the quality of the runners, with horses that have won certain values of races giving weight to less successful entrants.
Causality conditions In the study of Lorentzian manifold spacetimes there exists a hierarchy of causality conditions which are important in proving mathematical theorems about the global structure of such manifolds. These conditions were collected during the late 1970s.The weaker the causality condition on a spacetime, the more unphysical the spacetime is.
Taxation in the United States The United States of America has separate federal, state, and local governments with taxes imposed at each of these levels. Taxes are levied on income, payroll, property, sales, capital gains, dividends, imports, estates and gifts, as well as various fees.
Stock market A stock market, equity market, or share market is the aggregation of buyers and sellers of stocks (also called shares), which represent ownership claims on businesses; these may include securities listed on a public stock exchange, as well as stock that is only traded privately, such as shares of private companies which are sold to investors through equity crowdfunding platforms. Investment is usually made with an investment strategy in mind.
Animal Animals (also called Metazoa) are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development.
Chief executive officer A chief executive officer (CEO), also known as a central executive officer (CEO), chief administrator officer (CAO), or just chief executive (CE), is one of a number of corporate executives charged with the management of an organization – especially an independent legal entity such as a company or nonprofit institution. CEOs find roles in a range of organizations, including public and private corporations, non-profit organizations and even some government organizations (notably state-owned enterprises).
List of Intel processors This generational list of Intel processors attempts to present all of Intel's processors from the pioneering 4-bit 4004 (1971) to the present high-end offerings. Concise technical data is given for each product.
Internet In finance and economics, interest is payment from a borrower or deposit-taking financial institution to a lender or depositor of an amount above repayment of the principal sum (that is, the amount borrowed), at a particular rate. It is distinct from a fee which the borrower may pay the lender or some third party.
Target market A target market is a group of customers within a business's serviceable available market at which a business aims its marketing efforts and resources. A target market is a subset of the total market for a product or service.
Competition (biology) Competition is an interaction between organisms or species in which both require a resource that is in limited supply (such as food, water, or territory). Competition lowers the fitness of both organisms involved, since the presence of one of the organisms always reduces the amount of the resource available to the other.In the study of community ecology, competition within and between members of a species is an important biological interaction.
Significant figures Significant figures (also known as the significant digits, precision or resolution) of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something.\nIf a number expressing the result of a measurement (e.g., length, pressure, volume, or mass) has more digits than the number of digits allowed by the measurement resolution, then only as many digits as allowed by the measurement resolution are reliable, and so only these can be significant figures.
Significant other The term significant other (SO) has different uses in psychology and in colloquial language. Colloquially "significant other" is used as a gender-neutral term for a person's partner in an intimate relationship without disclosing or presuming anything about marital status, relationship status, gender identity, or sexual orientation.
Bit numbering In computing, bit numbering is the convention used to identify the bit positions in a binary number.\n\n\n== Bit significance and indexing ==\n\nIn computing, the least significant bit (LSB) is the bit position in a binary integer representing the binary 1s place of the integer.
Significant form Significant form refers to an aesthetic theory developed by English art critic Clive Bell which specified a set of criteria for what qualified as a work of art.
Statistical significance In statistical hypothesis testing, a result has statistical significance when it is very unlikely to have occurred given the null hypothesis. More precisely, a study's defined significance level, denoted by \n \n \n \n α\n \n \n {\displaystyle \alpha }\n , is the probability of the study rejecting the null hypothesis, given that the null hypothesis is true; and the p-value of a result, \n \n \n \n p\n \n \n {\displaystyle p}\n , is the probability of obtaining a result at least as extreme, given that the null hypothesis is true.

Significant Mother Significant Mother is an American television sitcom created by Erin Cardillo and Richard Keith. Starring Josh Zuckerman, Nathaniel Buzolic and Krista Allen, it premiered on The CW network on August 3 and ended its run on October 5, 2015.
Regulation Regulation is the management of complex systems according to a set of rules and trends. In systems theory, these types of rules exist in various fields of biology and society, but the term has slightly different meanings according to context.
Regulation A In the United States under the Securities Act of 1933, any offer to sell securities must either be registered with the United States Securities and Exchange Commission (SEC) or meet certain qualifications to exempt it from such registration. Regulation A (or Reg A) contains rules providing exemptions from the registration requirements, allowing some companies to use equity crowdfunding to offer and sell their securities without having to register the securities with the SEC. Regulation A offerings are intended to make access to capital possible for small and medium-sized companies that could not otherwise bear the costs of a normal SEC registration and to allow nonaccredited investors to participate in the offering.
Regulation (European Union) A regulation is a legal act of the European Union that becomes immediately enforceable as law in all member states simultaneously. Regulations can be distinguished from directives which, at least in principle, need to be transposed into national law.
Regulation of therapeutic goods The regulation of therapeutic goods, defined as drugs and therapeutic devices, varies by jurisdiction. In some countries, such as the United States, they are regulated at the national level by a single agency.
New York Codes, Rules and Regulations The New York Codes, Rules and Regulations (NYCRR) contains New York state rules and regulations. The NYCRR is officially compiled by the New York State Department of State's Division of Administrative Rules.
Radio regulation Radio regulation refers to the regulation and licensing of radio in international law, by individual governments, and by municipalities.\n\n\n== International regulation ==\nThe International Telecommunication Union (ITU) is a specialized agency of the United Nations (UN) that is responsible for issues that concern information and communication technologies.
Risk Factors
SUPERTEX INC Item 1A Risk Factors The following are certain risk factors that could affect our business, financial results and results of operations
These risk factors should be considered in connection with evaluating the forward-looking statements contained in this Annual Report on Form 10-K because these factors could cause the actual results and conditions to differ materially from those projected in the forward-looking statements
Investing in our common stock involves risks, including those described below
If any of the risks actually occur, our business, financial condition or results of operations could be negatively affected
In that case, the trading price of our common stock could decline, and you may lose all or part of your investment
Factors Which May Affect Operating Results Semiconductor companies as a group are subject to many similar risks
These include the risks that (1) the demand for semiconductors decreases as the industry has historically been very cyclical, (2) there are shortages of raw materials and/or fab capacity, or (3) there are changes in underlying circuit or process technology or fab technology
Other factors that could affect our future results include whether we can generate new bookings from both new and current products; general economic conditions, both in the United States and foreign markets, and economic conditions specific to the semiconductor industry; risks associated with customer concentration; our ability to introduce new products, to enhance existing products, and to meet the continually changing requirements of our customers; our ability to maintain and enhance relationships with our assembly and test subcontractors and independent distributors and sales representatives; and whether we can manufacture efficiently and control costs
In addition, we are subject to the risks described below, which are specific to our business: · We have focused our product offerings primarily on niche markets which leverage our capabilities and in which we believe we have dominance because we are the technology enabler for our customers
We attempt to choose markets which are sizable enough to be worth pursuing but which are not large enough to attract fierce competition
These markets could grow sufficiently to attract increased competition or else competitors could enter due to happenstance or downturns elsewhere
In addition, our niche market might be more susceptible to shrinkage than more diverse markets, due to their concentration on a few product offerings
· We work with our customers to develop products which they will design into their systems
Even if we do achieve a design win, the customer’s system may never go into production or the production may be smaller than we had anticipated
Although we attempt to develop products which will be useful for multiple customers, we may misjudge the market and develop a product which maybe useful for only very few customers
· We are dependent upon one fab which we own and operate
Were this fab to become unable to meet our needs for causes such as, obsolescence due to process technology changes, our ability to produce our products would be adversely affected
In addition, we could encounter difficulties in operating our fab, such as contaminants in the air or defects in equipment, which could affect yields and production
· We have several competitors that are substantially larger and could bring to bear substantially more resources in our niche markets
We have been able to maintain profitable margins in part because of our dominance of most of our niche markets
Increased competition could cause our margins to decrease
· Our gross margins may fluctuate depending on many factors, including, but not limited to, our product mix, competitive pricing dynamics, product yields, various manufacturing cost, plant utility, provisions for excess and obsolete inventory, and absorption of manufacturing overhead
· Henry Pao, a director of and the President and CEO of the Company, along with Mr
Pao’s father and brother, collectively own greater than 22prca of our outstanding stock
They have no agreement among themselves to act together with respect to the Company or their stockholdings
However, were they to act in concert, they would be our largest beneficial shareholder and would have an ability to elect one or more directors, to direct management, and to delay or prevent a change in control
10 _________________________________________________________________ · Our operations may be interrupted and our business would be harmed in the event of an earthquake, terrorist act, and other disasters
Our principal executive offices, our fab facility, and major suppliers are located in areas that have been subject to severe earthquakes
In the event of an earthquake, we and/or our major suppliers may be temporarily unable to continue operations and may suffer significant property damage
Any such interruption in our ability or that of our major suppliers to continue operations at our facilities could delay the development and shipment of our products
Like other US companies, our business and operating results are subject to uncertainties arising out of the economic consequences of current and potential military actions or additional terrorist activities and associated political instability, and the impact of heightened security concerns on domestic and international travel and commerce
Such uncertainties could also lead to delays or cancellations of customer orders, a general decrease in corporate spending or our inability to effectively market and sell our products
Any of these results could substantially harm our business and results of operations, causing a decrease in our revenues
· We sell a substantial amount of our products internationally
International sales represents 63prca, 44prca and 43prca of net sales, for fiscal years 2006, 2005 and 2004, respectively
We expect our international sales to continue to account for a significant portion of our total sales
We also package and test most of our products abroad
Problems with foreign economies, political turmoil, wars, epidemics, fluctuations in currency exchange rate, increased freight costs, interruptions in air transportation, and generally longer receivable collection period
These adverse conditions could disrupt our business and increase our operating expenses
· A significant portion of our sales is from a small number of customers and the loss of the one of these customers or failure to collect a receivable from them could adversely affect our operations and financial position
In fiscal 2006, two of our customers, Multi-Fineline, a contract manufacturer and YEL, a distributor of our products accounted for 13prca and 12prca of our net sales, respectively
We estimate that approximately 90prca of the combined sales to Multi-Fineline and YEL were subsequently sold to one end-user customer, a major communication equipment company
We do not have a long-term distributorship agreement with any of our distributors
Normal terms and conditions of sale apply, which include a 60-day notice of cancellation and charges for work-in-process for cancellations less than 60 days from shipment
While we have maintained a good relationship with our significant customers and distributors, deterioration in that relationship could materially and adversely affect our business and financial results
· We are dependent upon continued innovation by our engineers
The competition for engineers with relevant experience is extremely intense in the Silicon Valley, where most of our engineers are located
We must compete in terms of salary, benefits, and working conditions with many start-ups which can offer more equity
We established an IC Design Center in Hong Kong in fiscal 2001 where competition for qualified engineers is not as intense as that in Silicon Valley
However, a majority of our process technology and product innovation activities remains in our Sunnyvale and San Jose offices
· We operate a fab in San Jose, California at which we use various chemicals and solvents which are regulated by various environmental agencies
We cooperate and work with these agencies to comply with these regulations
Should we nonetheless inadvertently contaminate the soil or ground water, or should the previous operator of the fab have done so, we may be responsible for significant costs to remediate the situation
· We are dependent upon the continued service of several of our key management and technical personnel
The loss of the services of one or more of our engineers, executive officers and other key personnel or our inability to recruit replacements for, or to attract, retain and motivate these individuals would be harmful to our business
We do not have long-term employment contracts with our employees
11 _________________________________________________________________ · Our success depends upon our ability to protect our intellectual property, including patents, trade secrets, and know-how, and to continue our technological innovation
We cannot assure that the steps we have taken to protect our intellectual property will be adequate to prevent misappropriation or that others will not develop competitive technologies or products
The failure to obtain necessary licenses or other rights could cause us to lose market share and harm our business
· The Sarbanes-Oxley Act of 2002 required us to change or supplement some of our corporate governance and securities disclosure and compliance practices
The SEC and NASDAQ have revised, and continue to revise their regulations and listing standards
These developments have increased, and may continue to increase, our legal compliance and financial reporting costs
These developments also may make it more difficult and more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage
This, in turn, could make it more difficult for us to attract and retain qualified members of our board of directors, or qualified executive officers
Failure to comply with present or future laws, rules and regulations of any kind that govern our business could result in suspension of all or a portion of production, cessation of all or a portion of operations, or the imposition of significant administrative, civil, or criminal penalties, any of which could harm our business
· We are subject to taxation by domestic and foreign taxing authorities
Our business is subject to the application of multiple, and sometimes, conflicting tax laws and regulations
The application of tax laws is subject to legal and factual interpretation, judgment and uncertainty, and tax laws themselves are subject to change
Consequently, taxing authorities from various jurisdictions may impose tax assessments or judgments against us that could result in a significant change to earnings related to prior periods, and or an increase in our effective income tax rate
· Changes in stock option accounting rules scheduled to go into effect at the start of our fiscal 2007 will increase our compensation expense which will result in lower reported operating results prepared in accordance with generally accepted accounting principles
In addition, this pronouncement (SFAS 123R) may negatively impact our future stock price which could limit our ability to utilize broad based employee stock plans to reward employees and could result in a competitive disadvantage to us in the employee marketplace
