No full textDue to the extremely high pulse peak power produced by ultrafast laser and its potential applications for precious material processing and cutting e.g. sapphire wafer surface processing for mobile phone display technology, it has attracted great interests from the laser photonic industry. Apart from Semiconductor Saturable Absorber Mirror (SESAM), the carbon based materials e.g. carbon nano tube or graphene and graphene oxide materials have demonstrated mode locking successfully by using different types of gain materials with operational wavelengths at near 1 micron, 1.3 micron, 2 micron, confirming their wide operational waveband properties. These carbon based absorbers can be fabricated by some simple technique that can be used for mass production of the absorber e.g. dip coating, ultrasound, chemical process etc

Conjugacy separability of Seifert 3-manifold groups over non-orientable surfaces
No full textAbstractScott (1978) [12] showed Seifert 3-manifold groups are subgroup separable. Niblo (1992) [9] improved this result by showing that these groups are double coset separable. In Allenby, Kim and Tang (2005) [2] it was shown that all but two types of groups in the orientable case are conjugacy separable. Martino (2007) [7] using topological results showed that Seifert groups are conjugacy separable. Here we use algebraic method to show that Seifert groups over non-orientable surfaces are conjugacy separable

Abstract
Objectives
To assess the effectiveness of various approaches of dry needling (DN) for patients with knee pain and dysfunction
Search strategy
Six electronic databases: CINAHL Complete, Cochrane Library, EMBASE, Medline, PubMed, and PsycINFO were searched in November 2020 (registration number: CRD42021221419).
Screening
Risk of bias assessment and qualitative analysis were conducted by two independent reviewers using the PEDro scale.
Data management and reporting
Eight of 14 articles that met the inclusion criteria were high-quality manuscripts based on the PEDro scale. DN demonstrated positive short-term effects (from immediately after DN to <3 months) in pain reduction for both knee osteoarthritis (KOA) and patellofemoral pain syndrome (PFPS) (overall standardized mean difference [SMD]=-1.549, P=0.002). Subgroup analysis, however, revealed only significant improvement in PFPS (SMD=-3.435, P<0.001). At three months post-intervention, DN induced significant pain reduction in both KOA and PFPS (overall SMD=-0.916, P=0.022). Moreover, DN resulted in significant short-term improvement in function (overall SMD=6.069, P<0.001) in both KOA and PFPS. However, only PFPS showed a significant functional improvement in the subgroup analysis (SMD=6.089, P<0.001). At three months post-intervention, DN-induced functional improvement was significant in both groups (overall SMD=5.840, P<0.001), although only PFPS showed a significant improvement in the sub-group analysis (SMD=5.694, P=0.002). The outcomes of ultrasound (US)-guided DN on patients with knee pain are still unknown.
Conclusion
DN provides short-term benefits with respect to reducing pain and dysfunction for patients presenting with knee pain due to PFPS, but not KOA. Future research on US-guided DN for the treatment of knee pain is highly recommended
