Temporal hollowing is inevitable after decompressive craniectomy. This complication affects self-perception and quality of life, various techniques materials have therefore been used to restore patients' confidence. Autologous fat grafting in postoperative scar tissue has considered challenging because the hostile environment. However, this study, we demonstrate that autologous can be a simple safe treatment choice, even for depressed temporal tissue.Autologous was performed 13 patients from...
The demand for mobile DRAM has increased, with a requirement high density, data rates, and low-power consumption to support applications such as 5G communication, multiple cameras, automotive. Thus, density increased from 2Gb [1] 16Gb [2] in LPDDR4 LPDDR4X, but the maximum LPDDR5 is only 12Gb [3] due limited package size specification: 496-ball FBGA. In this work, mosaic architecture introduced increase 16Gb, even size. Additionally, I/O performance improved by shortening length top metal,...
Neurofibromatosis type 1 is the most common tumor predisposition syndrome inherited in an autosomal dominant (100% penetrance) fashion with a wide variety of expressivity. From perspective plastic surgery, significant clinical symptoms, including disfiguration, peripheral neurologic and skeletal abnormalities, are caused by various tumors originating from affected nerves. Surgical removal standard care for these tumors. However, outcome frequently unsatisfactory, facilitating search...
The need for high-quality multi-media data increases the amount of to be stored and processed, necessitating DDR5 achieve high-density high-speed with low-power consumption [1]. However, operation makes DRAM more vulnerable process-voltage-temperature (PVT) variations, negative-bias thermal instability (NBTI), etc. In this work, a mono-die based 24-Gb achieving 6.4Gbps/pin is implemented. To lower power consumption, GIO switching reduced by using separation switch read-only pre-charge...
This paper proposes a continuous-rate referenceless clock and data recovery (CDR) circuit operating in the half-rate clocking mode with jitter-tolerant frequency acquisition technique. The proposed coarse detector reduces error below 40,000 ppm without any sub-harmonic lock even when input jitter presents up to 0.6 UI <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pp</inf> . deadzone-compensated further residual 1,000 for following PLL's...
Recently, interest of general public toward ubiquitous home network has immensely increased and wireless PAN (personal area network) attracted strong attentions as short-distance networking solution. Convenience technology more over traditional wired devices such Ethernet, PLC HomePNA since it requires no cabling work. In the future, server will be combined with robot to provide functionalities identical current service well implement effective spontaneous server. this paper, embedded board...
Recently, when updating the products for Windows-based agents, an integrity breaches by malicious files or unusual behavior of product user\'s intentional modulation / deletion is causing a frequent accident cases. The PC based such as anti-virus, personal firewall (integrated security), data loss prevention, security USB and network access control that perform functions Agent on Windows operating systems, itself gets attacked becomes neutralized has existence vulnerabilities bypass...
Neoadjuvant chemotherapy (NACT) followed by total mastectomy and immediate reconstruction has become an important strategy in the treatment of breast cancer. Although safety subpectoral implant-based with NACT been extensively evaluated, prepectoral not clearly elucidated. We aimed to evaluate association outcomes.
Abstract Background Despite the increasing popularity of free tissue transfer, thigh defects have been alienated from their potential indication, owing to abundance regional reconstruction options. However, some challenging situations where locoregional modalities may lead suboptimal outcomes often require flap. Due lacking studies regarding microvascular defects, this study aimed investigate versatility transfer for defects. Methods A retrospective review was performed patients who...
The pure CrN powders oxidized to <TEX>$Cr_2O_3$</TEX> noticeably above <TEX>$850^{\circ}C$</TEX> in air. When these were sintered into bulk samples at <TEX>$1500^{\circ}C$</TEX> under 40 atm of <TEX>$N_2$</TEX> pressure, the phase partly changed <TEX>$Cr_2N$</TEX> phase, owing partial loss nitrogen from CrN. sample was heated <TEX>$1000-1200^{\circ}C$</TEX> for 100 hr vacuum, also progressively <TEX>$Cr_2N$</TEX>. At same time, a relatively thin layer formed on due reaction chromium with...
A two-phase boosted voltage (VPP) generator circuit was proposed for use in giga-bit DRAMs. It reduced the maximum gate oxide of pass transistor and lower limit supply to VPP V/sub TN/ respectively while those conventional charge pump are VPP+VDD 1.5 respectively. Also pumping current increased new circuit.
Tap inputs on the back of smartphones provide a solution to occlusion problem but come with challenges such as reduced accuracy and constrained functionality. In this work, we introduce MagTap, novel magnetic-based input interface for smartphones, specifically leveraging magnets ferromagnetic materials recognize tap made smartphones. Through our evaluation MagTap prototype an Apple iPhone 12, demonstrate that can achieve high localization (e.g., average 95.3% single taps 88.2% double taps),...
Polyimide (PI) is one of the most pragmatic polymers for highly durable flexible devices based on its micro- and nanopatterned structures, because excellent thermal chemical stability. The conventional top-down patterning processes, typically involving materials removal etching, however, are often ineffective to fabricate nanopatterns PI film due high mechanical resistance. In this work, we develop a efficient scalable methodology by utilizing burr- etch-free direct deformation driven...
