ATTENTION:
I have re-released the update with a critical fix for NAND-X/JR-P users. Apologies for the oversight - with such a complex update this slipped past me. This fixes reading/writing incorrect size issues.
I dont think its a wiring or power sequence issue, As its the same result on two consoles and it did work flawlessly on a trinity a couple days before. I'll try with a Win7 VM and see, was the only thing i didnt test.
So the problem is, my X-Flasher doesn't really work that good in eMMC mode. In this mode it constantly looses the connection with the console and crashes J-runner. Sometimes I manage to dump 2MBs of NAND, sometimes 4, sometimes 40, but very rarely it allows me to dump/write the full NAND.
I uncovered a condition where there is a 6-8", stop and start again, break in the top J-Runner in a 2Hour shaftwall assembly. This is on multiple floors in a stairwell . Can I use speed spray to bridge that gap, on one side of the wall? The shaftwall is continuous. It's like the contractor didn't want to cut an extra J-Runner so he just used two stock lengths from either end and was okay with leaving the gap.
Hi Elizabeth,
Great question. Unfortunately, because the framing or J-Runner is an integral part of the UL wall design, we would be unable to provide a fire rated engineering judgement to restore the rating of the assembly. Because there is a section with no J-runner, this alters the UL design of the assembly and therefore cannot be considered a rated assembly.

LoGuidice tossed a gem in game two holding the Owls hitless until the top of the seventh inning. LoGuidice retired 12 Owls in a row from the bottom of the second inning until Chatfield led off the bottom of the seventh with a single to right. LoGuidice faced just four batters over the minimum and recorded a pair of walks and four strikeouts en route to his first victory of the season.
In the control transfers, two out of eight growths from uterine blastocysts contained differentiated embryos, as compared with one out of 21 from oviducal stages. The single recognizable embryo from an oviducal stage developed from an eight-cell egg (Plate I, fig. F). When oviducal eggs were cultured to the blastocyst stage and then transferred, a total of nine out of 29 growths (31%) contained differentiated embryos (Plate 1, fig. G). This compares well with the proportion of embryos developing from uterine blastocysts, both in the present study and in earlier work (Kirby, 1962), and differs significantly from the fate of oviducal eggs transferred direct to the kidney (P < 001). Unlike in the testis series, the blastocysts from two-cell eggs differentiated into embryos as frequently as did those from eight-cell eggs.
Nicholas (1933,1942) also reported that two- to four-cell rat eggs gave rise to disorganized embryonic elements following transplantation to the kidney. Again this has not withstood recent investigation (Kirby, 1962), and Bland & Donovan (1965) have shown that neither oviducal nor uterine eggs of the guinea-pig develop into embryos in the testis or kidney.
The Canes finally broke through in the sixth, as TylerPalmer opened the frame with a double and junior Alex Hernandez followed upwith a single. With runners on the corners, Mack hit a ball that landed justfair in right field. Palmer scored easily, but Hernandez was tagged out at homeon a nice defensive relay from FAU. Mack, who took third on the throw, wouldlater score on a wild pitch from reliever Michael Sylvestri, cutting thedeficit to 3-2.
Ben Lindbergh and Meg Rowley banter about the end of the NLCS, discuss the discourse surrounding the improbability of and fallout from the Diamondbacks-Rangers World Series matchup, banter about the Brewers always losing in the playoffs to eventual pennant winners, preview the World Series, postulate a conspiracy surrounding this postseason's lack of extra-inning games, and react to the Red Sox hiring ex-pitcher Craig Breslow as their new Chief Baseball Officer/POBO, then (54:14) Stat Blast about how the World Series and future postseasons might be swayed by a reliever familiarity effect that could counter the pitcher-usage changes caused by the times-through-the-order penalty and restore longer starts, including a chat (1:12:06) with reliever-familiarity-effect researcher Dr. David J. Gordon.
Practitioners, for example, must deal continually with irritating roadblocks: incessant pressures from federally mandated regulations, myriad constraints imposed by insurance companies, for-profit-not-for-patients hospital administrators, lawsuits lurking around every corner, absurdly expensive malpractice premiums, reams of paperwork, and, finally, meager reimbursements.1
In response to these impediments, some practitioners have changed their specialty, some now limit their practices to the office, and some have become hospitalists. Others have sold their practices to hospitals or other health-related organizations and continue working as employees. Although a growing number of practitioners have simply given up and retired early, most have stayed put, battling to survive with no end to their struggles in sight.5
No matter what our response, it is easy to feel sorry for ourselves. But things could always be worse, as the story of the one-legged runner illustrates. If anyone had the right to feel sorry for himself, that guy did. After all, his adversity was permanent: he could never grow another leg. Yet, whatever he might have felt, he didn't give in or give up. He did what he could with what he had.
Background: In eutherian mammals, the sex chromosome complement, XX and XY, determines sexual differentiation of gonadal primordia into testes and ovaries, which in turn direct differentiation of germ cells into haploid sperm and oocytes, respectively. When gonadal sex is reversed, however, the germ cell sex becomes discordant with the chromosomal sex. XY females in humans are infertile, while XY females in the mouse (Mus musculus) are subfertile or infertile dependent on the cause of sex reversal and the genetic background. This article reviews publications to understand how the sex chromosome complement affects the fertility of XY oocytes by comparing with XX and monosomy X (XO) oocytes. Summary: The results highlight 2 folds disadvantage of XY oocytes over XX oocytes: (1) the X and Y chromosomes fail to pair during the meiotic prophase I, resulting in sex chromosome aneuploidy at the first meiotic division and (2) expression of the Y-linked genes during oocyte growth affects the transcriptome landscape and renders the ooplasmic component incompetent for embryonic development. Key Message: The XX chromosome complement gives the oocyte the highest competence for embryonic development.
The XO female mouse has a smaller ovarian reserve. In the XO oocyte, the single X chromosome is missing its pairing partner and fails in homologous synapsis, which provokes the meiotic silencing of unsynapsed chromosomes (MSUC) [Baarends et al., 2005; Turner et al., 2005; Cloutier et al. 2015, 2016]. Since silencing of X-linked genes is variable, the XO oocyte may survive or die depending on the repertoire of silenced genes [Cloutier et al., 2016]. An alternative explanation for the XO oocyte loss is the haplodeficiency of X-linked gene products. The ratio of X-linked versus autosomal gene transcript levels is lower in XO oocytes than in XX oocytes from the onset of meiosis [Sangrithi et al., 2017; Hamada et al., 2020]. However, our study has shown comparable numbers of oocytes between XO and XX ovaries on the B6 genetic background until birth [Alton et al., 2008; Vaz and Taketo, unpubl. data]. Therefore, the haplodeficiency of X-linked gene products appears to exert little effect on the oocyte survival in fetal life. After birth, the oocyte population declines in the XO ovary to half or as low as 15% of that in the XX ovary, dependent on the genetic background [Burgoyne and Baker 1981; Vaz et al., 2020]. This postnatal XO oocyte loss can be prevented by ablation of H2AFX phosphorylation, which is essential for exerting MSUC [Fernandez-Capetillo et al., 2003; Cloutier et al., 2015]. Therefore, MSUC rather than the haplodeficiency of X-linked gene products appears to contribute to the greater neonatal XO oocyte loss. It remains an open question whether the genetic background affects the MSUC efficiency or the survival of oocytes with a deficiency in X-linked gene products. The XO oocytes that have survived in neonatal ovaries can produce offspring, but the smaller ovarian reserve reflects in a shorter reproductive life span [Burgoyne and Baker 1981; Vaz et al., 2020].
The fate of XY germ cells in the ovary is more complex and controversial. Sakashita et al. [2019] have generated XYSry- sex-reserved mice on the B6 genetic background by deleting a part of the Sry gene using the CRISPR/Cas9 system. They reported fewer germ cells at embryonic day 13.5, prior to the onset of meiosis, and a subsequent delay in the onset of meiosis in the XYSry- ovary compared to the XX ovary. Furthermore, the XYSry- oocytes exhibit various abnormalities with the meiotic chromosomal configuration during the MPI progression, and their population diminishes rapidly by 8 days after birth. The authors speculated that expression of some Y-linked genes contributes to the meiotic defects, resulting in oocyte demise. We reported a different sequence of events in the B6.YTIR female mouse carrying an intact Y chromosome. Neither the onset of meiosis nor the initial oocyte population differs between the B6.YTIR and XX ovaries [Park and Taketo, 2003]. However, in the B6.YTIR ovary, there is a total loss of oocytes in the medullary region, where the oogonia first enter meiosis. Consequently, this region remains lacking oocytes until folliculogenesis begins postnatally [Villalpando et al., 1993]. The total number of oocytes is initially not affected because more oogonia are recruited into meiosis [Park and Taketo, 2003]. Thus, the most advanced MPI stage in the B6.YTIR ovary is delayed by one day compared to the XX ovary. After birth, another wave of major oocyte loss occurs, as reported for the XYSry- ovary. Recent study in our laboratory showed that the neonatal oocyte loss in the B6.YTIR ovary is comparable to that in the XO ovary on the B6 genetic background, suggesting that the greater XY oocyte loss can be largely attributed to the monosomy X, not the presence of the Y chromosome [Vaz and Taketo, unpubl. data]. In agreement with this conclusion, similar selective oocyte loss in the medullary region has been reported in the XO ovary on the B6 genetic background [Miura et al., 2017]. To our knowledge, no other XY female model has been examined as to the fate of oocytes in detail during fetal and neonatal development.
