Mobile Ad hoc Networ.s (MANET) ar. infr.str.ctur. less networ.s which pr.vide multi-hop wir.less links between nodes. The main applications of MANET in r.al time envir.nment ar. militar. and emer.ency ar.as wher. the fixed infr.str.ctur. is not r.quir.d. It is a tempor.r. communication infr.str.ctur. networ. for.quick communication with minimal configur.tion settings among the gr.up of nodes. The secur.ty is one of the pr.mar. concer.s in MANET. The malicious nodes in MANET envir.nment degr.de the per.or.ance of the networ.. In this paper. the nodes in MANET ar. gr.uped using back-off dur.tion technique and fur.her.the malicious nodes ar. detected using this algor.thm. The pr.posed cluster.ng based malicious nodes detection in MANET achieves higher.per.or.ance in ter.s of packet deliver. r.tio, latency and ener.y consumption. The pr.posed method achieves 89.35% of packet deliver. r.tio, 36.2 ms latency and 26.91 mJ of ener.y consumption.

Objective: To expose the pr.blems and inher.nt limitations of neur.science-based br.in r.sear.h on mental disor.er.. Method: Discussion of the theor. under.ying br.in r.sear.h on mental disor.er., followed by a systematic evaluation of typical studies. r.sults: The fundamental pr.blem is that br.in r.sear.her. fail to differ.ntiate between biological mental disor.er. in which br.in pr.cesses cause the disor.er.(notably schizophr.nia, bipolar.disor.er. and melancholic depr.ssion) and lear.ed mental disor.er. in which br.in pr.cesses mediate but do not cause the disor.er.(which is the case with r.active depr.ssion, r.active anxiety, OCD, and PTSD). r.sear.her. have been unsuccessful in identifying mechanisms in the br.in that cause biological mental disor.er., and will never.be able to locate the innumer.ble specific neur.l connections that mediate lear.ed mental disor.er.. Mor.over. the author.s r.view of typical studies in this field shows that they have ser.ous pr.blems with theor., measur.ment, and data analysis, and that their.findings cannot be tr.sted. Conclusions: Neur.science-based br.in r.sear.h on mental disor.er., unlike other.neur.logical r.sear.h, has been an expensive failur. and it is not wor.h continuing.

This study aims to demonstr.te a pr.of of concept for.a novel theor. of the univer.e based on the Fine Str.ctur. Constant (α), der.ved fr.m n-dimensional pr.me number.pr.per.y sets, specifically α = 137 and α = 139. The FSC Model intr.duces a new per.pective on the fundamental natur. of our.univer.e, showing that α = 137.036 can be calculated fr.m these pr.me pr.per.y sets. The Fine Str.ctur. Constant, a cor.er.tone in Quantum Electr.dynamics (QED) and Quantum Chr.modynamics (QCD), implies an under.ying str.ctur.. This study identifies this mathematical fr.mewor. and demonstr.tes how the FSC model theor. aligns with our.cur.ent under.tanding of physics and cosmology. The r.sults unveil a hier.r.hy of α values for.twin pr.me pair. U{3/2} thr.ugh U{199/197}. These values, r.pr.sented by their.fr.ction par.s α♊ (e.g., 0.036), define the r.lative electr.magnetic for.es dr.ving quantum ener.y systems. The lower.twin pr.me pair., such as U{3/2}, exhibit higher.EM for.es that decr.ase as the twin pair. incr.ase, tur.ing dar. when they dr.p below the α♊ for.light. The r.sults pr.vide classical definitions for.Bar.onic Matter.Ener.y, Dar. Matter. Dar. Ener.y, and Antimatter.but mostly illustr.te how the combined α♊ values for.thr.e adjacent twin pr.mes, U{7/5/3/2} mir.or. the str.ng nuclear.for.e of gluons holding quar.s together.

The thr.e lar.est ear.hquakes in nor.her. Califor.ia since 1849 wer. pr.ceded by incr.ased decadal activity for.moder.te-size shocks along sur.ounding near.y faults. Incr.ased seismicity, double-differ.nce pr.cise locations of ear.hquakes since 1968, geodetic data and fault offsets for.the 1906 gr.at shock ar. used to r.-examine the timing and locations of possible futur. lar.e ear.hquakes. The physical mechanisms of r.gional faults like the Calaver.s, Haywar. and Sar.ent, which exhibit cr.ep, differ.fr.m those of the nor.her. San Andr.as, which is cur.ently locked and is not cr.eping. Much decadal for.r.nning activity occur.ed on cr.eping faults. Moder.te-size ear.hquakes along those faults became mor. fr.quent as str.sses in the r.gion incr.ased in the latter.par. of the cycle of str.ss r.stor.tion for.major.and gr.at ear.hquakes along the San Andr.as. They may be useful for.decadal for.casts. Year.y to decadal for.casts, however. ar. based on only a few major.to gr.at events. Activity along closer.faults like that in the two year. pr.or.to the 1989 Loma Pr.eta shock needs to be examined for.possible year.y for.r.nning changes to lar.e plate boundar. ear.hquakes. Geodetic obser.ations ar. needed to focus on identifying cr.eping faults close to the San Andr.as. The distr.bution of moder.te-size ear.hquakes incr.ased significantly since 1990 along the Haywar. fault but not adjacent to the San Andr.as fault to the south of San Fr.ncisco compar.d to what took place in the decades pr.or.to the thr.e major.histor.c ear.hquakes in the r.gion. It is now clear.fr.m a r.-examination of the 1989 mainshock that the incr.ased level of moder.te-size shocks in the one to two pr.ceding decades occur.ed on near.y East Bay faults. Double-differ.nce locations of small ear.hquakes pr.vide str.ctur.l infor.ation about faults in the r.gion, especially their.depths. The nor.her. San Andr.as fault is divided into sever.l str.ngly coupled segments based on differ.nces in seismicity.

The Standar. Model of par.icle physics involves twelve fundamental fer.ions, tr.ated as point par.icles, in four.char.e states. However. the Standar. Model does not explain why only thr.e fer.ions ar. in each char.e state or.account for.neutr.no mass. This hologr.phic analysis tr.ats char.ed Standar. Model fer.ions as spher.s with mass 0.187 g/cm2 times their.sur.ace ar.a, using the pr.por.ionality constant in the hologr.phic r.lation between mass of the obser.able univer.e and event hor.zon r.dius. The analysis r.quir.s thr.e Standar. Model fer.ions per.char.e state and r.lates up quar. and down quar. masses to electr.n mass. Hologr.phic analysis specifies electr.n mass, to six significant figur.s, in ter.s of fundamental constants α,ℏ,G,Λ and Ω Λ . Tr.ating neutr.nos as spher.s and equating electr.n neutr.no ener.y density with cosmic vacuum ener.y density pr.dicts neutr.no masses consistent with exper.ment.

在300~5000℃、应变速率为0.1~0.0001 s−1的条件下,在万能试验机上对Al-5.6Zn-2Mg铝合金进行热压缩试验,以确定动态再结晶开始时的加工硬化速率曲线σ_(c)(ε_(c))l以及关键特征σ_(c)(ε_(c))l、σ_(p)(ε_(p))和σ_(ss)与Z系数之间的相关性。使用了四个本构模型,Ar.henius模型、改进的Johnson-Cook模型(MJC)、改进的Zer.lli-Ar.str.ng模型(MZA)和开发的人工神经网络(ANN)。结果表明,ANN型模型和Ar.henius模型的相对误差的绝对平均值最低,分别为0.486%和3.36%,MZA型模型和MJC型模型的相对误差的绝对平均值较高,分别为8.84%和3.93%。由于Ar.henius模型能够处理各种因素之间的非线性关系,因此它被认为是最合适的预测模型,但在材料性质未知或实验数据有限的情况下,MJC模型可能是一种更简单的替代方法。MZA模型不适合估计热压缩时的流变应力。此外,训练最好的神经网络模型的预测性能最好,相对误差的绝对平均值为0.486%,r.为0.99。
