Prediction of individual sequences is investigated for cases in which the decision maker observes a delayed version of the sequence or is forced to issue his her predictions a number of steps in advance with incomplete information For nite action and observation spaces it is shown that the prediction strategy that minimizes the worst case regret with respect to the Bayes envelope is obtained th...
This experiment was designed to test the hypothesis that delayed insemination of nonestrous cows would increase pregnancy rates when using sex-sorted semen in conjunction with fixed-time artificial insemination (FTAI). Estrus was synchronized for 656 suckled beef cows with the 7-d CO-Synch + controlled internal drug release (CIDR) protocol (100 μg GnRH + CIDR [1.38 g progesterone] on d 0, 25 mg...
ارائه و بهینه سازی یک مدل ریاضی چندهدفه مسئله یبارانداز تقاطعی با استفاده از الگوریتم های فراابتکاری
در این نوشتار یک مدل جدید چندهدفه ی بارانداز تقاطعی ارائه می شود. در مدل ریاضی این مقاله سه هدف کمینه سازی زمان کل عملیات حمل ونقل، کمینه سازی هزینه ی حمل ونقل، وکمینه سازی تعداد دفعات حمل ونقل در کل زنجیره ی تأمین در نظر گرفته شده است. از آنجا که مسئله ی بارانداز تقاطعی متعلق به رده ی n p-h a r d است و زمان حل مسئله با افزایش ابعاد مسئله به شدت افزایش می یابد، برای پیدا کردن جواب های نزدیک بهی...
BACKGROUND A combination of aprepitant, a 5-HT3 receptor antagonist (r.a.), and dexamethasone is recommended for the prophylaxis of cisplatin-induced nausea and vomiting in the acute phase, and aprepitant + dexamethasone (A + D) in the delayed phase. The aim of this study was to verify if A + D is superior to metoclopramide plus dexamethasone (M + D) in preventing delayed emesis in cancer patie...
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
با توجه به صلب بودن طرح‌های جامع و تفضیلی در برنامه‌ریزی کاربری اراضی شهری، توجه به تغییرات کاربری‌ها و مدلسازی آنها کمک شایانی در برآورد تأثیر تغییرات خواهد نمود. بررسی تأثیر تغییر کاربری‌های شهری در چینش سایر کاربری‌ها و معیارهای طراحی مانند سازگاری، وابستگی، مناسبت و سرانه‌ها به لحاظ محاسباتی مسئله‌ای چندهدفه بوده و جزء مسائل سخت رده‌بندی می‌شود. زیرا به‌دلیل تنوع بالای کاربری¬ها در محیط شهر...
In contrast to actively growing, susceptible plants which usually respond very promptly to applied 2,4dichlorophenoxyacetic acid (2,4-D), certain perennials that have been treated toward the end of a growing season may not exhibit morphological responses until the following season (9, 10, 12, 13). It has been a moot question whether (a) such delayed responses are initiated in sensitive cells of...
Weanling pigs (n = 176), 21 to 26 d of age (average initial weight, 7.1 kg), were used to evaluate the effects of weaning time (evening vs morning) and feeding time (immediate vs delayed) on postweaning performance. Pigs were randomly allotted within litters to four treatments in a 2 x 2 factorial arrangement as follows: 1) weaning at 2000 with immediate feeding, 2) weaning at 2000 with 12-h de...
Intraperitoneal gelatin sponge implants were used in guinea-pigs to examine the effect of D-penicillamine on the delayed hypersensitivity reaction in vivo. When it was administered daily in a dose of 200 mg/kg for 14 days before sensitisation or for 14 or 30 days before challenge, D-penicillamine increased the number of exudate cells during the onset of the delayed hypersensitivity reaction. Ab...
Ninety-two normal elderly persons were administered the Continuous Visual Memory Test (CVMT) on two occasions an average of 1.1 years apart. Means for age and education were 69.02 years (SD = 5.79) and 14.80 years (SD = 2.64), respectively. Stability coefficients were.49 on the Total score,.44 on d-prime, and.48 on Delayed Recognition. D-Prime and Delayed Recognition scores demonstrated signifi...
