STRAW consists of two $$150\,\mathrm {m}$$ 150 m long mooring lines instrumented with optical emitters and detectors. The pathfinder is designed to measure the attenuation length of the water and perform a long-term assessment of the optical background at the future P-ONE site. After 2 years of continuous operation, measurements from STRAW show an optical attenuation length of about 28 m at $$450\,\mathrm {nm}$$ 450 nm . Additionally, the data allow a study of the ambient undersea background. The overall optical environment reported here is comparable to other deep-water neutrino telescopes and qualifies the site for the deployment of P-ONE.

Female patients over the age of 18 years who attended an outpatient ophthalmology clinic were invited to participate. Schirmer's test, tear film break-up time and the ocular surface disease index questionnaire were used as objective and subjective clinical tests for dry eye. The cellular biomarker microtubule-associated protein light chain 3 (LC3) was used as a marker of autophagic cell death. Low LC3 nuclear staining was positively correlated with Schirmer's test <10 mm. No correlation was found between other clinical tests for dry eye. This study demonstrates a positive linear relationship between Schirmer's testing and LC3. There is a lack of correlation between the commonly used diagnostics ...

A significant increase of BTBT on STI edge sidewall was observed with non-optimized STI process, which suffers more seriously LOD effect. The defect enhanced boron diffusion model integrated the STI stress effect on defect generation is used to explain this observation. The BTBT degradation is attributed to the STI sidewall boron dopant enhanced diffusion and increased junction electric field of STI sidewall. This boron diffusion is random and more seriously in SRAM cell, thus results in worse pass-gate device mismatch and Vcc_min of 65nm node SRAM.

We propose an efficient algorithm called Riemannian manifold learning (RML). A Riemannian manifold can be constructed in the form of a simplicial complex, and thus its intrinsic dimension can be reliably estimated. Then the NLDR problem is solved by constructing Riemannian normal coordinates (RNC). Experimental results demonstrate that our algorithm can learn the data's intrinsic geometric structure, yielding uniformly distributed and well organized low-dimensional embedding data.

Based on an algebraic construction of orthonormal M-band wavelets with perfect reconstruction, the polyphase matrix can be factorized into a finite sequence of elementary reversible matrices that map integers to integers reversibly. We show that the reversible integer mapping is essentially equivalent to the lifting scheme, thus we extend the classical lifting scheme to a more flexible framework.

It was found that devices with super-steep-retrograde (SSR) indium channel profile depict higher transconductance in linear region, albeit the saturation drive current is lower, compared to the conventional BF2-doped control. In addition, In-doped devices also depict improved DIBL, I on–I off current ratio and transistor breakdown voltage. Finally, by increasing the indium implant energy, devices depict an improved transconductance, reduced DIBL and hot-carrier degradation, while suffering larger junction leakage and capacitance.

We consider both Str and T r prescriptions for the trace over gauge indices of the non-BPS action. Non-abelian tachyon condensation in the theory with T r prescription, and the resulting fluctuations about the kink profile, are shown to give rise to a theory of two coincident BPS D8-branes. This is a natural non-abelian generalization of Sen's mechanism of tachyon condensation on a single non-BPS Dp-brane yielding a single BPS brane of codimesion one. By contrast, starting with the Str gauge trace prescription of the coincident non-BPS D9-brane action, such a generalization of Sen's mechanism appears problematic.

With this mini-spacer, thicker corner liner oxide and a T-shaped trench oxide can be formed simultaneously. The issue of oxide-recess at STI corner can be effectively reduced and larger process window for subthreshold kink free device were obtained. The isolation capability and junction integrity were both improved as compared with those of the conventional STI process. Reverse narrow width effect as well as gate oxide integrity were also improved. This technology was employed for 0.13 µm complementary metal oxide silicon (CMOS) device fabrication.
