On the relaxed area of maps from the plane to itself taking three values
No full textIn this thesis we address two different problems; the first and the main one is the study of the relaxed area functional A(u, Ω) of the graph of vector maps u ∈ L1(Ω; R^k) on an open set Ω ⊂ R^n, mainly for n = k = 2. In particular we are interested in estimating from above the area of the graph of a singular map u taking a disk to three vectors, the vertices of a triangle, and jumping along three C^2-embedded curves that meet transversely at only one point of the disk. We show that the singular part of the relaxed area can be estimated from above by the solution of a Plateau-type problem involving three entangled nonparametric area-minimizing surfaces. The idea is to “fill the hole” in the graph of the singular map with a sequence of approximating smooth two-codimensional surfaces of graph-type, by imagining three minimal surfaces, placed vertically over the jump of u, coupled together via a triple point in the target triangle. Such a construction depends on the choice of a target triple point, and on a connection passing through it, which dictate the boundary condition for the three minimal surfaces. We show that the singular part of the relaxed area of u cannot be larger than what we obtain by minimizing over all possible target triple points and all corresponding connections. Moreover we investigate the possibility of adopting similar techniques to study the same problem in more general and different settings for instance when u has several (finite or infinite) triple junctions, or when n = 3, or when R^{2×2} is endowed by a Riemannian metric. An interesting open problem that we plan to address in the future, is to investigate the lower bound inequality; this seems to involve a strong use of geometric measure theory and Cartesian currents.
The second part of the thesis is devoted to the problem of characterizing arbitrary codimensional smooth manifolds M with boundary embedded in R^n using the square distance function and the signed distance function from M and from its boundary. The results are localized in an open set

No full textThe enactment of Law Number 18 of 2019 concerning Islamic Boarding Schools, followed by Regulation of the Minister of Religion of the Republic of Indonesia Number 32 of 2020 concerning Ma\u27had Aly, should be a hope for organizers and managers of education in the Islamic boarding school environment. These hopes include funding support and certainty of Ma\u27had Aly graduates. In addition, there is a legal guarantee for fulfilling the right to obtain employment opportunities and continue studies to the next level of education. Providing guarantees of recognition, affirmation, and facilitation for Islamic boarding schools based on their traditions and characteristics is a sociological and philosophical consideration when forming Islamic boarding school laws. To date, this guarantee has not been fully realized. The hope of Islamic boarding schools is still accompanied by the dilemma of ensuring recognition from the government. The author is interested in uncovering what the managers of Ma\u27had Aly are worried about, especially after the implementation of PMA Number 32 of 2020 concerning Ma\u27had Aly. The researcher\u27s focus is to describe the implementation of these regulatory policies. Because it concerns statutory norms, the method used in this research is normative juridical research, namely, literature study research, to examine PMA 32 of 2020. The aim is to describe the implementation of PMA 32 of 2020 for Islamic boarding schools that organize Ma\u27had Aly, the problems experienced by the management, and how the Ministry of Religion responds to the Islamic boarding school\u27s hesitation in implementing recognition, affirmation and facilitation policies. As a result, there are still problems for the organizers of Ma\u27had Aly. The external quality assurance system through the community assembly has not shown its productivity. The government, in this case, the Ministry of Religion, needs to be encouraged to have the courage to take strategic policy steps as a concrete form of recognition, affirmation and facilitation of Ma\u27had Aly implementation policies. Apart from that, the government is also encouraged to form a directorate general of Islamic boarding schools to solve bureaucratic problems in Islamic boarding school services
Differential expression of cytochrome oxidase and ALY-family genes in resistant and susceptible tomato cultivars (Solanum lycopersicum) inoculated with Tomato bushy stunt virus
No full textAbstractTomato cultivars (TY20, TY70/84 and TY70/70) were mechanically inoculated with purified virus preparations of Tomato bushy stunt virus (TBSV). Inoculated plant tissues were collected after 1day, 1week and 2weeks post-inoculation. Messenger RNA of the inoculated and healthy plants was scanned using the differential display to discover the up- and down-regulated genes induced or suppressed in the infected plants. Three down-regulated and four up-regulated genes were observed in different molecular weights. Sequence analysis revealed that the 400bp up-regulated gene of cultivars TY70/84 and TY70/70 was cytochrome oxidase gene. Expression of these genes was higher in the two resistant cultivars more than the control and the susceptible one (TY20). The other four genes belong to the ALY-gene family which possibly function as a chaperone to promote the interaction of DNA-binding proteins

Superconducting quantum point contacts and Maxwell potential
No full textThe quantization of the current in a superconducting quantum point contact is reviewed and the critical current is discussed at different temperatures depending on the carrier concentration as well by suggesting a constant potential in the semiconductor and then a Maxwell potential. When the Fermi wavelength is comparable with the constriction width we showed that the critical current has a step-like variation as a function of the constriction width and the carrier concentration. © World Scientific Publishing Company.Abdalla E, 1998, PHYS REV LETT, V80, P238, DOI 10.1103-PhysRevLett.80.238; AKAZAKI T, 1991, APPL PHYS LETT, V59, P2037, DOI 10.1063-1.106124; ALY AH, 1998, EGYPTIAN J PHYS, V70, P35; ANDREEV AF, 1964, SOV PHYS JETP-USSR, V19, P1228; Andreev A.F., 1964, Zhurnal Eksperimental'noi i Teoreticheskoi Fiziki, V46; BARDEEN J, 1972, PHYS REV B, V5, P72, DOI 10.1103-PhysRevB.5.72; Bauch T, 2005, PHYS REV B, V71, DOI 10.1103-PhysRevB.71.174502; BECKER T, 1995, PHYSICA B, V204, P183, DOI 10.1016-0921-4526(94)00261-S; Chang VCY, 1997, PHYS REV B, V55, P6004, DOI 10.1103-PhysRevB.55.6004; CHRESTIN A, 1994, PHYS REV B, V49, P498, DOI 10.1103-PhysRevB.49.498; Chtchelkatchev NM, 2000, PHYS REV B, V62, P3559, DOI 10.1103-PhysRevB.62.3559; Colatto LP, 2003, PHYS LETT A, V314, P184, DOI 10.1016-S0375-9601(03)00903-4; Dai Z, 2006, APPL PHYS LETT, V88, DOI 10.1063-1.2206697; De Franceschi S, 1998, APPL PHYS LETT, V73, P3890, DOI 10.1063-1.122926; DEGENNES PG, 1995, SUPERCONDUCTIVITY ME, pCH5; DESER S, 1982, ANN PHYS-NEW YORK, V140, P372, DOI 10.1016-0003-4916(82)90164-6; DUNNE GV, HEPTH9902115; FROLOV SM, 2004, MAT04042434; FURUSAKI A, 1991, PHYS REV LETT, V67, P132, DOI 10.1103-PhysRevLett.67.132; FURUSAKI A, 1998, CONDMAT9811026; FURUSAKI A, 1992, PHYS REV B, V45, P10563, DOI 10.1103-PhysRevB.45.10563; Giazotto F, 2001, APPL PHYS LETT, V78, P1772, DOI 10.1063-1.1357211; Imamura H, 2002, J APPL PHYS, V91, P7032, DOI 10.1063-1.1447188; ISHII C, 1970, PROG THEOR PHYS, V44, P1525, DOI 10.1143-PTP.44.1525; ISHII C, 1972, PROG THEOR PHYS, V47, P1464, DOI 10.1143-PTP.47.1464; KASTALSKY A, 1991, PHYS REV LETT, V67, P3026, DOI 10.1103-PhysRevLett.67.3026; Khare A, 1998, FRACTIONAL STAT QUAN; Kikuchi K., 2002, Physical Review B (Condensed Matter and Materials Physics), V65, DOI 10.1103-PhysRevB.65.020508; KLAPWIJK TM, 1994, PHYSICA B, V197, P481, DOI 10.1016-0921-4526(94)90248-8; KULIK IO, 1970, SOV PHYS JETP-USSR, V30, P944; Lachenmann SG, 1998, J APPL PHYS, V83, P8077, DOI 10.1063-1.367905; MAGNEE PHC, 1994, PHYS REV B, V50, P4594, DOI 10.1103-PhysRevB.50.4594; NGUYEN C, 1994, APPL PHYS LETT, V65, P103, DOI 10.1063-1.113047; NITTA J, 1992, PHYS REV B, V46, P14286, DOI 10.1103-PhysRevB.46.14286; Poirier W, 1997, PHYS REV LETT, V79, P2105, DOI 10.1103-PhysRevLett.79.2105; Regul J, 2002, APPL PHYS LETT, V81, P2023, DOI 10.1063-1.1506417; STERN J, 1991, PHYS LETT B, V265, P119, DOI 10.1016-0370-2693(91)90024-K; SVIDZINS.AV, 1973, J LOW TEMP PHYS, V10, P131, DOI 10.1007-BF00655245; Sze S.

Trade policies and trade mis-reporting in Myanmar
No full textWhile the trade statistics of Myanmar show surpluses for 2007 through 2010, the corresponding statistics of trade partner countries indicate deficits. Such discrepancies in mirror trade statistics are analyzed in connection with the ‘export-first and import-second’ policy provisioning import permissions on permission applicants possessing a sufficient amount of the export-tax-deducted export earnings. Under this policy, the recorded imports and exports of the private sector have been maintaining equilibrium, whereas discrepancies in the mirror statistics have fluctuated. This suggests that traders adjusted mis-reporting in accordance with the supply and demand of the export earnings.Myanmar, Trade policy, Trade problem, Trade Policies, Mis-invoicing, Smuggling

Box 2713, Doha, Qatar, Tel +974 4403 7856, Email [email protected]: The relationship between subclinical hypothyroidism and type 2 diabetes mellitus (T2DM) in Qatar is under-studied, despite the high prevalence of diabetes in the region. This study evaluates the potential association between subclinical hypothyroidism and T2DM in Qatar.Patients and Methods: A cross-sectional study used participants with and without T2DM from the Qatar Biobank (QBB). Logistic regression analysis was used to assess the association between subclinical hypothyroidism and T2DM, with multivariable logistic regression used to adjust for potential confounders.Results: The study found that subclinical hypothyroidism was significantly associated with a 2.82 increase in the odds of having T2DM (OR=2.82, 95% CI (1.13, 7.02), p=0.026) after adjusting for potential confounders. The proportion of subclinical hypothyroidism among individuals with T2DM in Qatar was 4.6%, significantly higher than in those without T2DM (2.8%, p=0.18).Conclusion: This study demonstrates a significant association between subclinical hypothyroidism and T2DM in Qatar. Further research is required to investigate the directionality of this association and its clinical implications.Keywords: cross-sectional, diabetes, hypothyroidism, subclinical hypothyroidism, T2D
