![]() Therefore, increased apoptosis may cause ECM remodeling and eventually result in the weakening of pelvic structures after various types of pelvic trauma, including pregnancy and vaginal delivery, pelvic surgery, or chronic abdominal pressure induced by chronic constipation. Apoptosis is involved in the pathogenesis and pathological process of many types of diseases, including extracellular matrix (ECM) remodeling after tissue injury. The nuclear translocation of Nrf2 can activate a series of antioxidant genes, such as glutathione peroxidase ( GPX), superoxide dismutase ( SOD), catalase ( CAT), and heme oxygenase-1 ( HO-1). Nuclear factor erythroid-2-related factor 2 (Nrf2) is a well-characterized global antioxidant gene inducer. Oxidative damage has been reported to be involved in mechanical trauma-induced PFD. Normal mechanical strain induces a physiological rise of ROS levels, while the excessive mechanical stress causes excessive ROS accumulation, eventually resulting in oxidative damage. Mechanical stress can induce the accumulation of reactive oxygen species (ROS). These data suggest that oxidative damage and apoptosis may contribute to PFD. Increased oxidative damage and apoptotic index have been reported in vaginal walls and pelvic connective tissues of PFD patients, especially in POP patients and patients with SUI induced by vaginal birth trauma or chronic abdominal pressure. This can cause traumatic slackness and alterations of the normal anatomical position and function of pelvic organs, resulting in SUI and/or POP. Vaginal delivery and chronic constipation or other causes of abdominal pressure increase the mechanical injury of pelvic connective tissues and muscular tissues. ![]() The vaginal wall plays an important role in maintaining the normal position and function of the vesical neck and urethra, which are attached to the anterior vaginal wall. The mechanical strength and toughness of the pelvic tissues are essential for maintaining the normal anatomical position and function of pelvic organs. The normal function of the female pelvic floor requires an intact anatomical structure, consisting of pelvic muscles, nerves, and connective tissues. Aging and vaginal delivery-induced pelvic injury are two of the most important risk factors of these disorders. Epidemiological studies indicate that SUI has significant adverse effects on women's everyday life and causes great economic burden. Stress urinary incontinence (SUI) is one of the most common types of PFD in women. Antioxidative therapy may be a promising treatment for mechanical trauma-related SUI.įemale pelvic floor dysfunction (PFD) is one of the most common benign gynecological diseases, which also include urinary incontinence (UI), pelvic organ prolapses (POP), and sexual dysfunction. Taken together, our data suggested that Nrf2 is a potential protective factor in mechanical trauma-induced apoptosis in a mouse model of SUI. The results showed that Nrf2 overexpression significantly alleviated VD-induced abnormalities in the anterior vaginal wall. To further confirm the role of Nrf2 in mechanical trauma-induced apoptosis and SUI, VD was performed on mice overexpressing Nrf2 via in vivo transfection of LV-Nfe2l2. The results showed that Nrf2 knockout aggravated VD-induced reduction in LPP, increase in cell apoptosis and peroxidation product levels, decrease in antioxidative protein activities, and alterations in apoptosis-related protein levels in the vaginal walls of mice. Leak point pressure (LPP) levels of apoptosis, apoptosis-related proteins, and peroxidation products and the activities of antioxidative proteins in the anterior vaginal wall were measured in wild-type (Nfe2l2 +/+) C57BL/6 mice and Nrf2-knockout mice (Nfe2l2 −/−). To test this hypothesis, a mouse model of vaginal distension- (VD-) induced SUI was established. Therefore, we predicted that Nrf2 may have a protective role in mechanical trauma-induced SUI. Nuclear factor erythroid-2-related factor 2 (Nrf2) is a well-characterized global antioxidant gene inducer that can reduce oxidative damage and apoptosis. Our previous results indicate that cell apoptosis and oxidative damage increase in a mouse model of mechanical injury-induced SUI and in fibroblasts treated with excessive mechanical strain. Apoptosis and oxidative damage are involved in the pathogenesis and progression of stress urinary incontinence (SUI).

The bit is the unit of data transfer, meaning that a communications device or system with a bandwidth of 8 MB has a transfer rate of 8 Megabits per second, which is equivalent to 1 Megabyte per second. A byte can represent values from 0 to 255. The Fortran BTEST function uses LSb 0 numbering. temp: BYTE temp AT temp : ARRAY0.7 OF BOOL tempX : BYTE tempX AT tempX : ARRAY0.7 OF BOOL tempL : BYTE tempL AT tempL : ARRAY0. A byte is a unit that consists of 8 bits. While high-bandwidth networks are often fast, that is not always the case. That feels like a bit (ha) of a waste, and it is. speed: 2 different measurements One point to consider when thinking about how to calculate bandwidth needs on your network is this: Bandwidth should not be confused with throughput, which refers to speed. C s normal storage options would mean devoting an entire char (8 bits) or int (16 bits) to keeping track of such tiny values. PL/I numbers BIT strings starting with 1 for the leftmost bit. When dealing with microcontrollers in particular, you will regularly have a small collection of sensors or switches that are providing on/off values. The value of an unsigned binary integer is therefore When the bit numbering starts at zero for the most significant bit (MSb) the numbering scheme is called MSb 0. MSb 0: A container for 8-bit binary number with the highlighted most significant bit assigned the bit number 0 the same hexadecimal number 0x12, again 00010010 in binary representation, will arrive as the (reversed) sequence 0 1 0 0 1 0 0 0. Least significant bit first means that the least significant bit will arrive first: hence e.g. the hexadecimal number 0x12, 00010010 in binary representation, will arrive as the sequence 0 0 0 1 0 0 1 0. Most significant bit first means that the most significant bit will arrive first: hence e.g. The expressions most significant bit first and least significant bit at last are indications on the ordering of the sequence of the bits in the bytes sent over a wire in a serial transmission protocol or in a stream (e.g. MSb stands for most significant bit, while LSb stands for least significant bit.īit weight for given bit position n ( 2 n ) We'll explore how computers can use bits and bytes to represent all types of information in this unit. It might even represent part of an audio recording or a pixel in an image. It might represent a number, a letter, or a program instruction. In this particular example, the position of unit value (decimal 1 or 0) is located in bit position 0 (n = 0). A byte represents different types of information depending on the context. This table illustrates an example of decimal value of 149 and the location of LSb. The expressions most significant bit first and least significant bit at last are indications on the ordering of the sequence of the bits in the bytes sent over a wire in a serial transmission protocol or in a stream (e.g. We also talk about them being true and false. This is actually pretty useful, as we can now set up constants for bit. Generally, we represent them with the numerals 1 and 0. So while there are 32 bits in an INTEGER, the bits range from 0 to 31, not 1 to 32. A binary number is made up of elements called bits where each bit can be in one of the two possible states. This allows the storage or transfer of digital information to remain concealed. Binary is a base-2 number system that uses two mutually exclusive states to represent information. Bytes, on the other hand, are used to express storage sizes. The user may later recover this information by extracting the least significant bits of the manipulated pixels to recover the original message. The bit rate refers to how many bits are transmitted per second. In digital steganography, sensitive messages may be concealed by manipulating and storing information in the least significant bits of an image or a sound file. Least significant bit in digital steganography This is often utilized in programming via bit shifting: A value of 1 << n corresponds to the n th bit of a binary integer (with a value of 2 n). Rather, it is a property of the numeric value in binary itself. For this reason, bit index is not affected by how the value is stored on the device, such as the value's byte order. In both cases, the LSb and MSb correlate directly to the least significant digit and most significant digit of a decimal integer.īit indexing correlates to the positional notation of the value in base 2. The MSb is similarly referred to as the high-order bit or left-most bit. The LSb is sometimes referred to as the low-order bit or right-most bit, due to the convention in positional notation of writing less significant digits further to the right. Similarly, the most significant bit ( MSb) represents the highest-order place of the binary integer. ![]() In computing, the least significant bit ( LSb) is the bit position in a binary integer representing the binary 1s place of the integer. But I usually write: /* Return type (8/16/32/64 int size) is specified by argument size.The unsigned binary representation of decimal 149, with the MSb highlighted.

Xiao Yan also associated with Wang's successor as prime minister, Emperor Wu's son Xiao Ziliang (蕭子良) the Prince of Jingling, and became one of eight young officials talented in the literary arts particularly befriended by Xiao Ziliang-along with Fan Yun, Xiao Chen (蕭琛), Ren Fang (任昉), Wang Rong (王融), Xie Tiao (謝朓), Shen Yue, and Lu Chui (陸倕). Wang was said to be impressed by Xiao Yan's talents and appearance, and he once said, "Mr. Xiao Yan was considered intelligent and handsome in his youth, and he started his career as a Southern Qi official by serving as military assistant for Emperor Wu's son Xiao Zilun (蕭子倫) the Prince of Baling, and later served on the staff of the prime minister Wang Jian. They had three daughters-Xiao Yuyao (蕭玉姚), Xiao Yuwan (蕭玉婉), and Xiao Yuhuan (蕭玉嬛), but no sons.Ĭareer as Southern Qi official and general Īround 481 or 482, Xiao Yan married Chi Hui (郗徽), the daughter of the Liu Song official Chi Ye (郗燁) and the Princess Xunyang. One of them, Xiao Xiu (475–518) is now mainly remembered because of his comparatively well-preserved funerary statuary ensemble near Nanjing. Xiao Yan had six other brothers born of Xiao Shunzhi's concubines. Lady Zhang died in 471, predating Xiao Shunzhi's becoming a marquess during Southern Qi. Xiao Yan was Xiao Shunzhi's third son, and his mother was Xiao Shunzhi's wife Zhang Zhirou (張至柔), who was also the mother of his older brothers Xiao Yi (蕭懿) and Xiao Fu (蕭敷), his younger brother Xiao Chang (蕭暢), and his younger sister Xiao Linyi (蕭令嫕). For Xiao Shunzhi's contributions, Xiao Daocheng created him the Marquess of Linxiang and made him a general. His father Xiao Shunzhi (蕭順之), who claimed ancestry from the great Han Dynasty prime minister Xiao He, was a distant cousin of the Liu Song general Xiao Daocheng, and was part of Xiao Daocheng's close circle of advisors in Xiao Daocheng's eventual seizure of the Liu Song throne and establishment of Southern Qi (as its Emperor Gao) in 479. Xiao Yan was born in 464, during the reign of Emperor Xiaowu of Liu Song. After shouting several times, the Emperor supposedly died of hunger and thirst. After Emperor Wu was imprisoned, he was thirsty and asked Hou for honey, but Hou refused to give it to him. The Emperor is the namesake of the Emperor Liang Jeweled Repentance (梁皇寳懺), a widely read and major Buddhist text in China and Korea.Īt the end of his reign, his unduly lenient attitude towards his clan's and officials' corruption and lack of dedication to the state came at a heavy price when the general Hou Jing rebelled (侯景之亂), few came to his aid, and Hou captured the imperial capital Jiankang, holding Emperor Wu and his successor Emperor Jianwen under close control and plunging the entire Liang state into anarchy. It was said that he received the Buddhist precepts during his reign, earning him the nickname The Bodhisattva Emperor. He banned the sacrifice of animals and was against execution. He himself was attracted to many Indian traditions. Although for governmental affairs he was Confucian in values, he embraced Buddhism as well. He was well read himself and wrote poetry and patronized the arts. He came from the same Xiao clan of Lanling (蘭陵蕭氏) that ruled the preceding Southern Qi dynasty, but from a different branch.Įmperor Wu established universities and extended the Confucian civil service exams, demanding that sons of nobles (士族) study.

Adobe Premiere Pro CC Crash at startup - no error Message ![]() Bonding the shield well to the shielded enclosure or adding on-board common mode chokes or installing an external common mode choke around the product end of the I/O cable are typical solutions. These higher frequency antennas are available from Q: What can you do if you notice the emissions noise is actually on the shield of the cable?Ī: That’s typically where you find these noise currents (also known as common mode currents) traveling along the outside of your shield. For very high (above 6 GHz) emissions, I use the smaller PC board log-periodic antennas and higher frequency broadband preamplifiers. Basically, I use the same tools and troubleshooting techniques. Q: what do you troubleshoot frequencies above 1GHz?Ī: Assuming you’re asking what tools and techniques I use for troubleshooting radiated emissions above 1 GHz. This should help you determine a “safe” margin when using your 3m chamber and may even provide the justification required by other country regulatory agencies. This will provide you a sort of calibration curve between the two measurement distances versus frequency. One thing you might consider is to take a comb generator with some standardized (electrically short) antenna and compare between your 3m chamber and a commercial 10m chamber. In other words, the assumption of “plane waves” is not quite true and so the distance factor from the product under test will also depend slightly on factors of 1/r^2 and 1/r^3 terms, rather than the simple 1/r term for plane waves. Finally, depending on the definition you use (typically 1/6 th wavelength), you’re approaching the near field at the lower frequencies. Also, the 4m antenna height can’t normally be achieved in a 3m chamber, so you’re not fully comparing the higher “take-off angles” of fields emanating from the product under test between the two measurement distances. I always suggest that margins from the limit be increased when using 3m chambers, if at all possible. The issue for 3m arises mainly at the lower frequencies (say, under 200 MHz) where the chances of reflection errors might be greater. How to justify this? Should final reports always be at a 10 m test site, not a 3 m chamber?Ī: While a 10m distance seems to have been adopted by the standards committees as a “standard”, not everyone can afford a 10m chamber. We are questioned by Japan as to why we do not use a 10 m chamber, since limits are in terms of 10 m in all of the standards, not 3m. Q: We typically use a 3m chamber to test our IVD instruments, as seems typical in the US and Europe. ![]() However, I’ve seen cases for radiated (and especially ESD and other impulse type signals) that will reset the microprocessor IC or cause glitching in digital signals. Q: For immunity, I thought an analog circuit was more susceptible than a digital circuit?Ī: Generally, you’re correct. Of course, the objective is to eliminate the common mode currents on all your cables so cable emissions don’t enter in to the equation! It really depends on how tight the folding is. Folding (serpentining) the cables tends to cancel the field in that section, but may produce a minor amount of vertical emission. If they droop over the edge of the table, they’ll generally produce a combination of horizontal and vertical emissions. If the cables are oriented horizontally, they’ll generally product horizontal polarized emissions if vertical, then vertical emissions. I’m assuming these are all cables attached to the product and spread out around the measurement table. For radiated immunity, I feed a small RF field into one of these small loops and run the field around the PC board, looking for areas of sensitivity.Ī: Good question. You’ll likely require a broadband preamplifier to boost the very low signals from the smaller probes. You can also make your own by fashioning a small loop at the end of a piece of small-size coaxial cable. Beehive Electronics, Aaronia, Langer and Rhode & Schwarz all make near field probes with very small loops that will yield good resolution. However, for identifying emission sources, I’d use a very small loop probe. For emissions, I’d test like any other board. How do you handle first EMC measurements for very small PC boards (like the size of a pencil)?Ī: I did have to evaluate a medical product with a very small PC board. ![]() Q: What you describe is good for big PC boards.
