Pendahuluan: warung kopi menjadi ikon masyarakat yang ada di kota-kota besar maupun kota berkembang untuk melakukan interaksi berupa pertemuan membincangkan hal serius cuma bercanda dan menghabiskan waktu luang namun ini sangat berbahaya saat dilakukan pada masa pandemi Covid-19 karena bisa media penularan penyakit tersebut. Tujuan: mengetahui faktor mempengaruhi kepatuhan pengunjung warkop pro...

Introduction: Acne vulgaris is a frequently encountered skin disease in daily practice. Its clinico-epidemiological status was evaluated in this study.Methods: Four hundred patients were studied by record-based observation for 2 years in the Acne Clinic of a tertiary care hospital.Results: This study revealed a male preponderance (53%) with a higher p...

Thedensity(ρ) and speed of sound (u)of the binarymixture (diethylene glycol monoethyl ether (carbitol) + propylene glycol (PG)) have been reported at T= (288.15, 298.15, 308.15 and 318.15) K. The excess molar volume ( ) and isentropic compressibility deviation (Δκs) were calculated using the measured data. The obtained values of ( ) and (Δκs) are negative and positive,...

In 1971, Schelling introduced a model in which families move if they have too many neighbors of the opposite type. In this paper, we will consider a metapopulation version of the model in which a city is divided into N neighborhoods, each of which has L houses. There are ρNL red families and ρNL blue families for some ρ < 1/2. Families are happy if there are ≤ ρ(c)L families of the opposite typ...

Let a∈ℤ and ρ be a root of f (x)=x 3 -ax 2 -(a+3)x-1, then the number field K =ℚ(ρ) is called simplest cubic field. In this paper we consider family unit equations u 1 +u =n where ,u ∈ℤ[ρ] * n∈ℤ. We completely solve under restriction |n|≤max{1,|a| 1/3 }.

We prove the following information-theoretic property about quantum states. Substate theorem: Let ρ and σ be quantum states in the same Hilbert space with relative entropy S(ρ‖σ) := Tr ρ(log ρ− log σ) = c. Then for all > 0, there is a state ρ′ such that the trace distance ‖ρ′ − ρ‖tr := Tr √ (ρ′ − ρ)2 ≤ , and ρ′/2O(c/ 2) ≤ σ. It states that if the relative entropy of ρ and σ is small, then there...
