Design
The KDL-46D3500 is the embodiment of Sony's design philosophy with a chic matte black understated presence that simply oozes class. Build quality is back to its very best with the Sony looking like it could have been sculpted from a solid block of metal.
Features
Unlike the KDL-40D3500, there is no corresponding 3000 model alongside the KDL-46D3500 in the UK. If you are familiar with the D3000 series from Sony it is worth noting that the 46D3500's spec sheet reads a little different than you would imagine.
Sony currently offer a huge range of LCD TV's and the number of different models can seem quite bewildering to those of you who are looking to buy a new LCD TV. The D3500 sits between the slightly higher spec V3000 series and directly above the slightly lower spec T3500 line.
Essentially, the D3500 gains 'True Cinema' over the T3500 but comes equipped with a slightly less sophisticated version of Sony's 'Bravia' picture processing engine than the V3000.

Sony KDL-46D3500 Review
Sharp LC42XL2E Review
With a slim (7.5cm) frame finished in black, with a glass bezel around the outside of the screen the LC42XL2E is an indication that Sharp is taking style much more seriously.
With 100Hz processing and 10-bit panels, Sharp's top of the range LC-42XL2E offers some additional features over the entry level LC-42X20E. 100Hz processing doubles the number of frames displayed on-screen for smoother pictures while 10-bit panels increase the number of available colours.

LG 50PC55 Review
Design
LG have realised that style sells and have employed an Italian design studio to improve on the rather clunky look of LG's of the past.
With its piano black minimalist look complemented by a stand in the same style, the 50PC55 looks like it could actually claw back sales that were lost as a result of previous models rather 'clunky' style. The finishing slim silver strip which separates the screen frame from the full length horizontal speaker at the units base completes a rather chic piece of kit that won't look out of place even in the most fashion conscious of households.
Features
Connectivity on the LG 42PC55 is adequate rather than outstanding, with 2 HDMI inputs along with 2 Scarts and the usual Composite video input, Component video input, S-video and PC input.
Picture processing technology on the 50PC55 comes in the shape of LG's proprietary XD engine. The XD Engine brings together a range of picture processing enhancements under the XD umbrella, and amongst other things focuses on improving the input signal quality.

HD ready
HD ready concerns the abilities of television receivers to display high-definition pictures. The term has had official use in Europe since January 2005 when, EICTA (European Information, Communications and Consumer Electronics Technology Industry Associations) announced the requirements for the label.
EICTA introduced the label as a quality sign for the differentiation of display equipment, capable of processing and displaying high-definition signals. It is awarded on the basis of minimum functionality requirements that are detailed in the "EICTA conditions for HD Labeling of Display Devices".
In the USA, "HD Ready" refers to any display that is capable of accepting and displaying a high-definition signal at either 720p, 1080i or 1080p using a component video or digital input, and does not have a built-in HD-capable tuner.
Alternatives to HD ready TVs
Many PCs and laptops are actually more HD ready, in the true sense of the phrase, than the HD ready label requires. They will not, however, qualify for the HD ready label, unless they also meet the connector requirements.
Any sufficiently fast computer with a 1280x720 or higher resolution display is capable of displaying HD video, even though computers are generally not advertised as such. This video may come from the Internet, data files, or a DTV tuner card. The Internet already offers some HD content, like movie and videogame trailers.

Sony KDL-40D3500 Review
The KDL-40D3500 is the embodiment of Sony's design philosophy with a chic matte black understated presence that simply oozes class. Build quality is back to its very best with the Sony looking like it could have been sculpted from a solid block of metal
A change in model number from 3000 to 3500 would suggest that the KDL-40D3500 represented a relatively minor upgrade from its predecessor the KDL-40D3000. However, the changes in specification are more wide ranging than you would imagine.
Genetic linkage
Genetic linkage occurs when particular genetic loci or alleles for genes are inherited jointly. Genetic loci on the same chromosome are physically connected and tend to segregate together during meiosis, and are thus genetically linked. Alleles for genes on different chromosomes are usually not linked, due to independent assortment of chromosomes during meiosis.
Because there is some crossing over of DNA when the chromosomes segregate, alleles on the same chromosome can be separated and go to different daughter cells. There is a greater probability of this happening if the alleles are far apart on the chromosome, as it is more likely that a cross-over will occur between them.
The relative distance between two genes can be calculated using the offspring of an organism showing two linked genetic traits, and finding the percentage of the offspring where the two traits do not run together. The higher the percentage of descendants that does not show both traits, the further apart on the chromosome they are.
Among individuals of an experimental population or species, some phenotypes or traits occur randomly with respect to one another in a manner known as independent assortment. Today scientists understand that independent assortment occurs when the genes affecting the phenotypes are found on different chromosomes or separated by a great enough distance on the same chromosome that recombination occurs at least half of the time.
An exception to independent assortment develops when genes appear near one another on the same chromosome. When genes occur on the same chromosome, they are usually inherited as a single unit. Genes inherited in this way are said to be linked, and are referred to as "linkage groups." For example, in fruit flies the genes affecting eye color and wing length are inherited together because they appear on the same chromosome.
But in many cases, even genes on the same chromosome that are inherited together produce offspring with unexpected allele combinations. This results from a process called crossing over. At the beginning of normal meiosis, a chromosome pair (made up of a chromosome from the mother and a chromosome from the father) intertwine and exchange sections or fragments of chromosome. The pair then breaks apart to form two chromosomes with a new combination of genes that differs from the combination supplied by the parents. Through this process of recombining genes, organisms can produce offspring with new combinations of maternal and paternal traits that may contribute to or enhance survival.
Genetic linkage was first discovered by the British geneticists William Bateson and Reginald Punnett shortly after Mendel's laws were rediscovered.

Smart Badges Track Human Behavior
In the corporate and academic worlds, conferences and networking events are necessary. But while some people trade business cards with aplomb, others clump with coworkers, rarely venturing beyond the safety of their pre-existing social circle. New research from MIT's Media Lab has shown that a sensor-laden conference badge might be able to help people venture out, form new connections, and gain insight into how they interact with others at such events.
Ben Waber, an MIT researcher who worked on the project (and blogged about it here), gave souped-up badges to 70 participants at a Media Lab event. These badges use an infrared sensor to gather data about face-to-face interactions, a wireless radio to collect data regarding proximity to other badges and send it to a central computer, an accelerometer to track motion of the participant, and a microphone to monitor speech patterns. At the event, the data from the infrared sensors was wirelessly transmitted to a computer that crunched the numbers,
producing a real-time visualization of the event's social graph.
This project illustrates the increasing popularity of sociometrics, a discipline in which sensors collect fine-grained data during social interactions and software makes sense of it.
Waber works with MIT professor Sandy Pentland, who is credited with much of the early work in sociometrics and coining the term "reality mining." (See "What Your Cell Phone Knows About You" and "The iPhone's Untapped Potential.") But Waber and Pentland aren't alone. Researchers at Intel are using sensors to help monitor the health and behavior of the elderly. And others are using position data gleaned from cell phones to help develop more-comprehensive models of how disease spreads.
In addition, an MIT spin-off company, nTag, provides smart badges similar to Waber's that automatically send out and receive "e-cards." While nTag's badges don't collect motion and voice data, they are capable displaying data as real-time visualizations of the social network at a conference, says Rick Borovoy, cofounder and chief technology office of the company.
Borovoy says that revealing a social network, in particular, can change the dynamics at a conference. "It creates a sense of community and identity, and it's a way to subtly intervene and disrupt conventional networking patterns," he says. Borovoy says that nTag has found that showing people their networking patterns on a social graph is enough to change them. "You think people know their patterns, but often they don't," he says.
