The text is the follower: \n\nThe electric field of an electromagnetic wave is:\n  $$E = E_0\\sin \\omega t (\\sin \\omega z,  \\cos \\omega z, 0 ). $$\n  I have to find the magnetic field $B$, then I have to verify the Maxwell equation for $E$ and $B$, and finally I have to find the 4-potential $A^\\mu$ in the Lorenz gauge.\n\nFirst of all, I have considered $n$ the direction of propagation of the wave:\n$n=(0,0,1)$\nSo that I thought B is the cross product of $n$ and E, I have obtained:\n$B= n \\times E = E_0\\sin \\omega t (-cos \\omega z,  sin \\omega z, 0 )$\nAnd this result seemed me reasonable, because the scalar product between E and B is null.\nIn empty space, I expect that the divergence of E and B is null, and in this case is verified. The other two Maxwell's equation establish:\n$\\nabla \\times E + \\frac{\\partial B}{\\partial t} =0 $\n$E_0 \\omega \\sin \\omega t (sin \\omega z,  cos \\omega z, 0 ) + E_0 \\omega \\cos \\omega t (-cos \\omega z,  sin \\omega z, 0 ) = E_0 \\omega (-cos(\\omega t + \\omega z), sin(\\omega t + \\omega z),0) $\nBut in this way the sine and the cosine can not vanish simultaneously, they have got the same argument !\n$\\nabla \\times B - \\frac{\\partial E}{\\partial t} =0 $\n$E_0 \\omega \\sin \\omega t (-cos \\omega z, sin \\omega z, 0 ) - E_0 \\omega \\cos \\omega t (sin \\omega z, cos \\omega z, 0 ) = E_0 \\omega (-sin(\\omega t + \\omega z), -cos(\\omega t + \\omega z), 0)$\nThere is the same problem as before.\nThen I have tried to obtain $A^\\mu$. \n$A = \\frac{B}{\\omega}$\n$\\nabla \\times A = \\nabla \\times \\frac{B}{\\omega} = \\frac{1}{\\omega} \\nabla \\times B = B$\nBecause I noticed \n$\\nabla \\times B = \\omega B$\nThen I wanted to obtain $A^0$\n$E = \\frac{\\partial A}{\\partial t} - \\nabla A^0$\nBut I stopped there because in my opinion there are too many errors in my reasoning. The Maxwell equation are not verified. \nIf someone has the solution, I will be to him infinitely grateful\n", "pair": "smith_vs_teacher", "system_left": "teacher", "system_right": "smith", "overall": "tie_both_good", "aspects": {"naturalness": "tie_both_good", "cultural_appropriateness": "tie_both_good", "instruction_following": "tie_both_good", "coherence": "tie_both_good"}, "comment": "", "instance_feedback": "", "winner_system": null, "annotator_id": "dreamy_hypatia", "session_id": "5242241903174d79b3df9bf02ee21fd9", "annotated_at": "2026-09-22T20:26:36", "duration_ms": 459339}

For example, terephthalic acid, a PET polymer precursor, is usually produced by aerial oxidation of p-xylene obtained from petroleum. A synthesis of terephthalic acid from renewable sources is possible but considerably more challenging. In this task, we will prepare a terephthalic acid derivative (7) starting from galactose (1). First, the galactose is fermented to produce mucic acid (2), which in turn is converted to 3-hydroxy-2-pyron-6-carboxylic acid (3) by dehydration. The acid (3) is then esterified using bioethanol from rapeseed (a typical Czech bioethanol source). The resulting ester 4 undergoes a base-catalyzed reaction with dimethyl maleate (5) to form compound 6, which is then hydrolyzed under acidic conditions to produce the final compound 7. The dimethyl maleate was synthesized using methanol (produced from synthesis gas) from maleic acid (8) obtained from a biological source. \n\nHow many carbon atoms of the product 7 originated from renewable sources?", "pair": "smith_vs_teacher", "system_left": "smith", "system_right": "teacher", "overall": "a", "aspects": {"naturalness": "a", "cultural_appropriateness": "tie_both_good", "instruction_following": "a", "coherence": "a"}, "comment": "", "instance_feedback": "", "winner_system": "smith", "annotator_id": "dreamy_hypatia", "session_id": "5242241903174d79b3df9bf02ee21fd9", "annotated_at": "2026-09-22T20:36:33", "duration_ms": 353668}

I saw this question Two-loop regularization\nand I found that the exact solution of above integration is very complex and need a lot of fancy technique. However in order to do the renormalization I need only singular part of $I(p)$ ($\\epsilon$-expansion with $D=4-\\epsilon$).\nMy question:\n\nIs there some easy and direct method just to compute the singular part of $I(p)$ i.e. the coefficient of $1/\\epsilon^2$ and $1/\\epsilon$? \n\nBy the way, I saw this answer https://physics.stackexchange.com/a/79236/169288 But it only give an explicit computation of singular of $I^\\prime(p^2=m^2)$ which is not my requirement. \nYou just need to provide the literature or textbooks which show the explicit computation details.
