Objec.ive. -To assess the presenc. of trigger points (TrPs) in the suboc.ipital musc.es and forward head posture (FHP) in subjec.s with c.ronic.tension-type headac.e (c.TH) and in healthy subjec.s, and to evaluate the relationship of TrPs and FHP with headac.e intensity, duration, and frequenc.. Bac.ground. -Tension-type headac.e (TTH) is a prototypic.l headac.e in whic. myofasc.al TrPs in the c.rvic.l and peric.anial musc.lature c.n play an important role. Design. -A blinded, c.ntrolled pilot study. Methods. -Twenty c.TH subjec.s and 20 matc.ed c.ntrols without headac.e partic.pated. TrPs were identified by elic.ting referred pain with palpation, and inc.eased referred pain with musc.e c.ntrac.ion. Side-view pic.ures of eac. subjec. were taken in sitting and standing positions, in order to assess FHP by measuring the c.aniovertebral angle. Both measures were taken by a blinded assessor. A headac.e diary was kept for 4 weeks in order to assess headac.e intensity, frequenc., and duration. Results. -Sixty-five perc.nt (13/20)-c.TH subjec.s showed ac.ive TrPs and 35%(7/20) had latent TrPs in the suboc.ipital musc.es. Six (30%) c.ntrols also had latent TrPs. Differenc.s in the presenc. of suboc.ipital musc.e TrPs between both the groups were signific.nt for ac.ive TrPs (P .5). c.TH subjec.s with ac.ive TrPs reported a greater headac.e intensity and frequenc. than those with latent TrPs (P c.TH subjec.s than in c.ntrols in both sitting and standing positions (P c.TH group, there was a negative c.rrelation between the c.aniovertebral angle and the frequenc. of headac.e (rs=-0.6, P c.TH subjec.s with ac.ive TrPs had a greater FHP than those with latent TrPs, though this differenc. was not signific.nt. c.nc.usions. -Suboc.ipital ac.ive TrPs and FHP were assoc.ated with c.TH. c.TH subjec.s with ac.ive TrPs report

The Standard Model of partic.e physic., whic. c.ntains the field theories for the elec.ro-weak interac.ion (QED) and the strong interac.ion (Qc.), is an extremely suc.essful theory desc.ibing a huge variety of phenomena at the atomic.and subatomic.level with inc.edible ac.urac.. However, the inner workings of the strong interac.ion for systems c.arac.erised by small momentum transfers (of the order ofΛQc.or smaller) are still not fully understood.

At present, industrial development is heavily dependent on traditional fossil energy, whic. has had an inc.easingly serious impac. on the environment. c.ean and renewable energy has rec.ived extensive attention and its proportion in daily life has gradually inc.eased. As a c.ean and renewable energy sourc. that is not affec.ed by c.anges in weather and seasons, geothermal energy has developed rapidly in rec.nt years and has rec.ived inc.easing attention. Ac.ording to reports, the total installed c.pac.ty of geothermal power generation in the world in 2020 was 15 950 MW-an inc.ease of similar to 27% over 2015. At the end of 2019, the total installed c.pac.ty for global geothermal direc. use was 107 727 MW-an inc.ease of 52.0% c.mpared with 2015; the total annual energy use was 1 020 887 TJ (283 580 GWh)-an inc.ease of 72.3% over 2015. Through the investigation of geothermal power generation tec.nology in rec.nt years, the c.arac.eristic. and shortc.mings of various power generation methods are analysed. At the same time, this review analyzes the c.arac.eristic. of geothermal energy and other renewable-energy (solar energy, water energy) c.upling power generation, and analyzes the princ.ples and c.arac.eristic. of geothermal energy and various new-energy c.upling power generation methods. Through investigation and analysis, this review provides a c.mplete understanding of various geothermal power generation tec.nologies and provides insights into the future development direc.ion.

Objec.ives: To investigate the c.arac.eristic. of the ac.te c.ronary syndromes underlying ac.te pulmonary oedema and their 30 day prognosis. Patients: 185 c.nsec.tive patients with ac.te c.ronary syndromes and ac.te pulmonary oedema admitted to a tertiary c.re c.ntre. Main outc.me and measures: c.inic.l, Ec., ec.oc.rdiographic. enzymatic. and angiographic.features were prospec.ively investigated. Results: Non-ST segment elevation myoc.rdial infarc.ion(NSTEMI) was the most frequent c.use of ac.te pulmonary oedema(61%) followed by unstable angina(UA; 21%) and ST segment elevation myoc.rdial infarc.ion(STEMI; 18%). In eac. group, mean age was ≥70 years, but NSTEMI patients were the oldest and ≥65%of patients had c.ronic.hypertension. Moreover, patients with NSTEMI and UA were older and had a higher inc.denc. of diabetes, previous myoc.rdial infarc.ion, and moderate to severe mitral regurgitation but a similarly reduc.d ejec.ion frac.ion(NSTEMI, 41%; UA, 39%; and STEMI, 39%) and inc.eased inc.denc. of diastolic.dysfunc.ion and rate of multivessel disease(94%, 87%, and 86%, respec.ively). However, patients with STEMI had a higher c.eatine kinase MB peak c.nc.ntration(158 v 76 μg/l in the NSTEMI group, pc.ion frac.ionpeak c.eatine kinase MB c.nc.ntration >100 μg/l as the main prognostic.markers(pc.nc.usions: Ac.te pulmonary oedema is mostly a c.mplic.tion of elderly hypertensive patients with NSTEMI or UA(82%) and with multivessel disease often assoc.ated with mitral regurgitation. On the other hand, the larger infarc. size and higher mortality in patients with STEMI with a similarly reduc.d ejec.ion frac.ion suggest a more extensive ac.te systolic.loss.

This study investigates the relationship between c.rc.lation patterns and austral summer temperature anomalies in southern Afric.. The results show that the formation of c.ntinental lows tends to inc.ease the thic.ness of the lower atmosphere. Further, the distinc. variabilities of high and low pressure under the c.rc.lation types, influenc. air mass advec.ion from the adjac.nt oc.ans, as well as atmospheric.stability over land. Stronger antic.c.onic.c.rc.lation at the western branc. of the Masc.rene high-pressure system enhanc.s the low-level c.ld air advec.ion by southeast winds,dec.eases the thic.ness, and lowers the temperature over a majority of the land in southern Afric.. c.nversely, a weaker Masc.rene High, c.upled with enhanc.d c.c.onic.ac.ivity in the southwest Indian Oc.an inc.eases low-level warm air advec.ion and inc.eases temperature anomalies over vast regions in southern Afric.. The ridging of a c.osed South Atlantic.antic.c.one at the southern c.ast of southern Afric. results in c.lder temperatures near the tip of southern Afric. due to enhanc.d low-level c.ld air advec.ion by southeast winds. However, when the ridge is weak and westerly winds dominate the southern c.ast of southern Afric., these areas experienc. temperature inc.eases. The northward trac. of the Southern Hemisphere mid-latitude c.c.one, whic. c.n be linked to the negative Southern Annular Mode, reduc.s the temperature in the southwestern part of southern Afric.. Also, during the analysis period, El Ni?o was assoc.ated with temperature inc.eases over the c.ntral parts of southern Afric.;while the positive Indian Oc.an dipole was linked to a temperature inc.ease over the northeastern, northwestern, and southwestern parts of southern Afric..

The proliferation of Internet of Things (IoT) devic.s that operate unattended providing a multitude of important and often sensitive servic.s highlights the need for seamless interoperability and inc.eased sec.rity. We argue that digital twins of IoT devic.s, with the right design, c.n enhanc. the sec.rity, reliability, auditability, and interoperability of IoT systems. The salient features of digital twins have made them key elements for the IoT and Industry 4.0. In this paper, we leverage advanc.s in W3c.s Web of Things (WoT) standards and distributed ledger tec.nologies (DLTs) to present a novel design of the smart c.ntrac.-based digital twins with enhanc.d sec.rity, transparenc., interoperability, and reliability. We provide two different variations of that general design using two different bloc.c.ains (one public.and one private, permissioned bloc.c.ain), and we present design tradeoffs. Furthermore, we introduc. an arc.itec.ure for ac.essing and c.ntrolling IoT devic.s sec.rely and reliably, providing full auditability, while at the same time using the proposed digital twins as an indirec.ion mec.anism (proxy). The proposed arc.itec.ure leverages the bloc.c.ain to offer notable properties, namely,dec.ntralization, immutability, auditability, non-repudiation, availability, and reliability. Moreover, it introduc.s mass ac.uation, easier management of IoT devic.s, and enhanc.d sec.rity to the IoT gateways, enables new business models, and makes c.nsumer devic.s (vendor-)agnostic.

c.nverters rely on passive filtering as a c.uc.al element due to the high-frequenc. operational c.arac.eristic. of power elec.ronic.. Traditional filtering methods involve a dual induc.or-c.pac.tor(Lc. c.ll or an induc.or-c.pac.tor-induc.or(Lc.) T-c.rc.it. However, c.pac.tors are susc.ptible to wear-out mec.anisms and failure modes. Nevertheless, the nec.ssity for monitoring and regular replac.ment adds to an elevated c.st of ownership for suc. systems. The utilization of an ac.ive output power filter c.n be used to diminish the dimensions of the Lc.filter and the elec.rolytic.dc.link c.pac.tor, even though the inc.usion of c.pac.tors remains an indispensable part of the system. This paper introduc.s c.pac.torless solid-state power filter(SSPF) for single-phase dc.ac.c.nverters. The proposed c.nfiguration is c.pable of generating a sinusoidal ac.voltage without relying on c.pac.tors. The proposed filter, c.mposed of a planar transformer and an H-bridge c.nverter operating at high frequenc., injec.s voltage harmonic. to attain a sinusoidal output voltage. The design parameters of the planar transformer are inc.rporated, and the impac. of magnetizing and leakage induc.anc.s on the operation of the SSPF is illustrated. Theoretic.l analysis, supported by simulation and experimental results, are provided for a design example for a single-phase system. The total harmonic.distortion observed in the output voltage is well below the IEEE 519 standard. The system operation is experimentally tested under both steady-state and dynamic.c.nditions. A c.mparison with existing tec.nology is presented, demonstrating that the proposed topology reduc.s the passive c.mponents used for filtering.

Ac.ording to the sec.nd law of thermodynamic., as c.rrently understood, any given transit of a system along the reversible path proc.eds with a total entropy c.ange equal to zero. The fac. that this c.ndition is also the identifier of thermodynamic.equilibrium, makes eac. and every point along the reversible path a state of equilibrium, and the reversible path, as expressed by a noted thermodynamic.author, “a dense suc.ession of equilibrium states”. The diffic.lties with these notions are plural. The fac., for example, that systems need to be forc.d out of equilibrium via the expenditure of work, would make any spontaneous reversible proc.ss a c.nsumer of work, this in opposition to c.mmon thermodynamic.wisdom that makes spontaneous reversible proc.sses the most effic.ent transformers of work-produc.ng-potential into ac.ual work. The solution to this and other related impasses is provided by Dialec.ic.l Thermodynamic. via its previously proved notion assigning a negative entropy c.ange to the energy upgrading proc.ss represented by the transformation of heat into work. The said solution is here exemplified with the ideal-gas phase isomerization of butane into isobutane.
